Introduction
The Thermo Scientific™ 43iQ Sulfur Dioxide (SO2) utilizes pulsed
fluorescence technology to measure the amount of sulphur dioxide in the
air.
The pulsing of the UV source lamp serves to increase the optical intensity
whereby a greater UV energy throughput and lower detectable SO2
concentration are realized.
Reflective bandpass filters, as compared to commonly used transmission
filters, are less subject to photochemical degradation and more selective in
wavelength isolation. This results in both increased detection specificity
and long term stability.
iQ Series
Instrument
Platform
Thermo Scientific
The iQ Series Instrument Platform is a smart environmental monitoring
solution for ambient and source gas analysis that affords greater control
over instrument performance and data availability.
●
Distributed Measurement and Control (DMC) module design
simplifies serviceability. Each DMC module contains its own
microprocessor control enabling functional performance validation
at the module level.
●
Built-in predictive diagnostics and preventive maintenance
schedules identify problems before they occur. The iQ Series
platform sends email notifications directly to Thermo Fisher
Scientific’s world class service support team or locally identified
addressees in order to proactively communicate analyzer
performance conditions and identify spare parts needs before an
operational concern arises.
●
The iQ Series platform supports Modbus, streaming and VNC
protocols over serial and Ethernet as well as analog and digital I/O
for easy integration into most data management systems.
●
Three standard USB ports afford convenient data download
capability as well as the ability to connect additional hardware, such
as a computer keyboard or mouse.
●
The iQ Series GUI runs on a 7” color touchscreen display. The
GUI is highly flexible and can be customized to enable a tailored

Thermo Scientific
Introduction
43iQ Principle of Operation
43iQ Principle of
Operation
The 43iQ operates on the principle that SO2 molecules absorb ultraviolet
(UV) light and become excited at one wavelength, then decay to a lower
energy state emitting UV light at a different wavelength. Specifically,
SO 2 h1 SO 2 * SO 2 h 2
The sample is drawn into the 43iQ through the SAMPLE bulkhead, as
shown in Figure 1–2. The sample flows through a hydrocarbon “kicker,”
which removes hydrocarbons from the sample by forcing the hydrocarbon
molecules to permeate through the tube wall. The SO2 molecules pass
through the hydrocarbon “kicker” unaffected.
The sample then flows into the fluorescence chamber, where pulsating UV
light excites the SO2 molecules. The condensing lens focuses the pulsating
UV light into the mirror assembly. The mirror assembly contains four
selective mirrors that reflect only the wavelengths which excite SO2
molecules.
As the excited SO2 molecules decay to lower energy states they emit UV
light that is proportional to the SO2 concentration. The bandpass filter
allows only the wavelengths emitted by the excited SO2 molecules to reach
the photomultiplier tube (PMT). The PMT detects the UV light emission
from the decaying SO2 molecules. The photodetector, located at the back
of the fluorescence chamber, continuously monitors the pulsating UV light
source and is connected to a circuit that compensates for fluctuations in the
UV light.
As the sample leaves the optical chamber, it passes through a flow sensor, a
capillary, and the “shell” side of the hydrocarbon kicker. The sample then
flows to the pump and is exhausted out the EXHAUST bulkhead of the
analyzer. The 43iQ outputs the SO2 concentration to the front panel
display and the analog outputs, and also makes the data available over the
serial or Ethernet connection.

Setup Procedure
Setup Procedure
Use the following procedure to setup the instrument:
1. Connect the sample line to the SAMPLE bulkhead on the rear panel
(Figure 2–5). Ensure that the sample line is not contaminated by dirty,
wet, or incompatible materials. All tubing should be constructed of
PTFE, 316 stainless steel, borosilicate glass, or similar tubing with an
OD of 1/4-inch and a minimum ID of 1/8-inch. The length of the
tubing should be less than 10 feet.
Note Gas must be delivered to the instrument free of particulates. It may
be necessary to use the PTFE particulate filter as described in “PTFE
Particulate Filter” on page 9-23. ▲
Note If the sample may contain particulates larger than 5 microns, it
should be filtered before introducing it to the instrument. Use a filter (such
as PTFE) that does not interact with SO2 in the sample. If a sample filter is
used, all calibrations and span checks must be performed through the filter.
The filter element should be replaced regularly to prevent the absorption of
SO2 by trapped material on the filter. ▲
Note Gas must be delivered to the instrument at atmospheric pressure. It
may be necessary to use an atmospheric bypass plumbing arrangement as
shown in Figure 2–6 if gas pressure is greater than atmospheric pressure. ▲
2. Connect the EXHAUST bulkhead to a suitable vent. The exhaust line
should be 1/4-inch OD with a minimum ID of 1/8-inch. The length of
the exhaust line should be less than 10 feet. Verify that there is no
restriction in this line.
3. If the optional zero/span solenoid valves are installed, connect a source
of SO2 and HC free air to the ZERO IN bulkhead, and connect a
source of SO2 span gas to the SPAN bulkhead.
4. Connect a suitable recording device to the rear panel connector. For
detailed information about connecting to the instrument, refer to:
“Connecting External Devices” on page 9-1
Communications > “Analog I/O” on page 3-80, and “Digital I/O”
on page 3-81.

Calibration
The Calibration screen allows the user to calibrate the system, setup

“Calibration” for further instructions on how to run a calibration.
The following screens show the calibration screens in single range mode
and dual or auto range mode. The dual and auto range modes have two
SO2 span factors (high and low). This allows each range to be calibrated
separately. This is necessary if the two ranges used are not close to one
another. For example, a low SO2 range of .5 ppm and a high SO2 range of
10 ppm. For more information about range modes, see “Range Mode
Selection” on page 3-65.

Averaging Time
The Averaging Time screen allows the user to choose dynamic filtering or a
manually selected (static) averaging time.
Averaging Time defines the time period (1 to 300 seconds) during which
SO2 measurements are taken. The average concentration of the readings are
calculated for that time period. The front panel display and analog outputs
are updated every second if averaging time is greater than 1 second. An
averaging time of 10 seconds, for example, means that the average
concentration of the last 10 seconds will be displayed at each update. An
averaging time of 300 seconds means that the moving average
concentration of the last 300 seconds will be the output at each update
(every 10 seconds). Therefore, the lower the averaging time the faster the
front panel display and analog outputs respond to concentration changes.
Longer averaging times are typically used to smooth output data.
Dynamic Filtering allows for data smoothing without compromising
response time. The instrument automatically changes the averaging time
giving the user faster response times when conditions are rapidly changing;
smoother and stable readings, when conditions aren’t changing as rapidly;
and as an added bonus, it better processes spikes to minimize their impact
on the data. At the same time it will preserve the representative nature of
the filtered data to the conditions being sampled.
Note When Dynamic Filtering is selected, the user selected Averaging
Time button is disabled. ▲

Range Mode Selection
The Range Mode Selection screen is used to switch between the various
range modes: Single, Dual, and Auto Range.
Home Screen>Settings>Measurement Settings>Range Mode Selection
The Range Mode Selection screen contains the following information:
●
Single: In single range mode, there is one range, one averaging time,
and one span coefficient.
●
Dual: In the dual range mode, there are two independent analog
outputs. These are labeled simply as the “High Range” and the “Low
Range”. Each channel has its own analog output range setting,
averaging time, and span coefficient.
This enables the sample concentration reading to be sent to the analog
outputs at two different ranges. For example, the low SO2 analog
output can be set to output concentrations from 0 to 50 ppb and the
high SO2 analog output set to output concentrations from 0 to 100
ppb.
In addition, each SO2 analog output has a span coefficient so that each
range can be calibrated separately. This is especially necessary if the two
ranges are not close to one another. For example, the low SO2 range is
set to 0–50 ppb and the high SO2 range is set to 0–10000 ppb.
●
Auto: The auto range mode switches the SO2 analog outputs between
high and low range settings, depending on the concentration level. The
high and low ranges are defined in the Range Settings screen.
For example, suppose the low range is set to 50 ppb and the high range
is set to 100 ppb, as shown below. Sample concentrations below 50
ppb are output based on low range selection and sample concentrations
above 50 ppb are output based on high range selection. When the low
range is active, the range mode selection status output is at 0 volts.
Thermo Scientific
43iQ Instruction Manual

Operation
Settings
When the high range is active, the range mode selection status output is
at half of full-scale.
When the high range is active, the concentration must drop to 95% of
the low SO2 range for the low range to become active.
In addition, each SO2 range and analog output has a span coefficient so
that each range can be calibrated separately. This is especially necessary
if the two ranges are not close to one another. For example, the low
SO2 range is set to 0–50 ppb and the high SO2 range is set to 0–10000
ppb.

Chapter 4
Calibration
This chapter describes the procedures for calibrating the analyzer and
describes the required equipment.
The 43iQ requires initial and periodic calibration according to the
procedures described in this chapter. A quality control plan that allows the
frequency and number of calibration points to be modified depending on
calibration and zero/span check data should be implemented. Such a
quality control program is essential to ascertain the accuracy and reliability
of the air quality data collected. The data compiled for such a program
might include items such as dates of calibration, atmospheric conditions,
control settings and other pertinent data. For more detailed quality
assurance guidelines, see the Quality Assurance Handbook for Air Pollution
Measurement Systems, published by the U.S. EPA, Research Triangle Park,
NC, 27711.
There are a number of conditions which should be met prior to a
calibration or a zero/span check. First, the instrument should have at least
30 minutes to warm up and stabilize. Second, the range used during the
calibration or zero/span check should be the same as that used during
normal monitoring. Third, all operational adjustments to the instrument
should be completed prior to calibration. Fourth, all parts of the gas flow
system, such as sample lines, and particulate filters, which are used in
normal monitoring should also be used during calibration. Finally, it is
recommended that the recording devices and outputs used during normal
monitoring be calibrated prior to the instrument calibration and that they
be used during the calibration or the zero/span check.
Equipment Required
The following equipment is required to calibrate the instrument:
●
Zero air
●
Calibration gas
Note In order to reduce the possibility of interferences during calibration,
all zero gas supplied to the instrument during calibrations should use air as
the zero gas and not nitrogen. The same recommendation also applies to
span gases supplied, where the calibration gas is supplied with a known SO2
concentration with the balance of gas as air and not nitrogen. ▲
Thermo Scientific
43iQ Instruction Manual 4-1
Calibration
Equipment Required
Zero Air Generation
An SO2-free (< 0.0005 ppb) air supply is required for the proper calibration
and checkout of the instrument. There are several methods that are
acceptable to generate this zero air.
Commercial Heatless Air
Dryers
Commercial heatless air dryers filled with a mixed bed of activated charcoal
and a 13X molecular sieve have been found effective in removing SO2 from
compressed air. The use of this type of zero gas system is recommended
when minimum maintenance is of prime importance. This system requires
a source of compressed air. Refer to the manufacturer’s recommendations
for installation of such a system.
Absorbing Column
An absorbing column packed with activated charcoal is acceptable for
scrubbing SO2 from ambient air. Ambient air is forced through a
laboratory gas absorption column packed with the charcoal and the SO2 is
removed to acceptable levels (<0.0005 ppb). The charcoal should be
changed at a minimum of every six months. It may be necessary to change
the charcoal more frequently depending on local conditions.
SO2 Concentration
Standard
A cylinder of SO2 in air containing an appropriate concentration of SO2
suitable for the selected operating range of the analyzer under calibration is
necessary. The assay of the cylinder must be traceable either to a National
Institute of Standards and Technology (NIST) SO2 in Air Standard
Reference Material (SRM) or an NIST/EPA approved gas manufacturer's
Certified Reference Material (CRM).
A recommended protocol for certifying SO2 gas cylinders against a SO2,
SRM or CRM is given in the Quality Assurance Handbook1. The SO2 gas
cylinder should be recertified on a regular basis determined by the local
quality control program.
Calibration Gas
Generation
4-2
43iQ Instruction Manual
A calibration gas system capable of providing accurate levels of SO2
calibration gas between zero and 80% of the full-scale range is required.
The calibration system must provide a flow rate of at least 0.5 LPM for an
instrument with the standard flow (instruments with higher flow rates will
require a higher minimum calibration system flow rate). All calibration gas
should be derived from local or working standards (such as cylinders of
compressed gas or permeation devices) that are certified as traceable to an
NIST primary standard.
Thermo Scientific
Calibration
Equipment Required
Cylinder Gas Dilution
A cylinder gas dilution system, shown in Figure 4–1, can be constructed.
All connections between components in the system should be made with
glass, SS, PTFE or other non-reactive material.
The air flow controller should be capable of maintaining a constant air flow
within ±2% of the required flow rate. The SO2 flow controller should be
capable of maintaining constant SO2 flows within ±2% of the required flow
rate. Ensure both flow controllers are properly calibrated. The pressure
regulator for the standard SO2 cylinder must have a non-reactive
diaphragm and internal parts and a suitable delivery pressure.
External Flow Meter(s)
and Controller(s)
In order to obtain an accurate dilution ratio in the dilution method used
for calibration, the flow rates must be regulated to 1%, and be measured to
an accuracy of at least 2%. The meter and controller can be two separate
devices, or combined in one device. The user's manual for the meter should
be consulted for calibration information.
Additional information on the calibration of flow devices can be found in
the Quality Assurance Handbook1. It should be noted that all flows should
be corrected to 25 °C and 760 mmHg, and that care should be exercised in
correcting for water vapor content.

The exact SO2 concentration is calculated from:
[ SO2 ] OUT =
[ SO2 ] STD x F SO2
F D + F SO2
Where:
[SO2]OUT = diluted SO2 concentration at the output manifold, ppm
[SO2]STD = concentration of the undiluted SO2 standard, ppm
FSO2 = flow rate of the SO2 standard corrected to 25 C and 760 mm Hg
FD = flow rate of the dilution air corrected to 25 C and 760 mm Hg
Commercial Precision
Dilution Systems
Commercial precision dilution systems are available which reliably and
accurately dilute a high concentration gas mixture to provide a reliable span
gas. A high concentration (50 ppm) of SO2 in air is precisely diluted to the
concentration range required.
The Thermo Scientific 146iQ Multi-gas Calibrator is one such system for
precision dilution.
Permeation Tube System
Permeation tube systems which precisely maintain a set temperature to
within ±0.1 °C and hold a zero air flow rate to within ±0.5% can be used
for generation of span gas. The flow rate of the permeation system must be
at least 0.5 LPM for proper operation.
A permeation tube system, shown in Figure 4–2 can be constructed. All
connections between components in the system should be made with glass,
PTFE, or other non-reactive material.
The air flow controllers should be capable of maintaining a constant air
flow within ±2% of the required flow rate. Ensure all devices are properly
calibrated and that all flows are corrected to 25 C and 1 atm.

Commercial permeation systems, such as the Thermo Scientific 146iQ
Multigas Calibration System, are available for this requirement. Refer to
the instrument instruction manual for more information.
In addition to the 146iQ and other commercial permeation systems, the
43iQ can also be configured with an optional permeation oven to supply
calibration gas for the instrument. The operation of the internal
permeation oven is described in Chapter 9, “Optional Equipment”.

Calibration
Calibration
Calibration
Regulations typically require zero/span calibration when the instrument is
newly installed, moved, repaired, interrupted for more than a few days, or
when span or zero shift by more than 15%.
All gas must be supplied to the instrument at atmospheric pressure. It may
be necessary to employ an atmospheric bypass plumbing arrangement to
accomplish this. Refer to Figure 2–6 in the “Installation and Setup” chapter
for an example of an atmospheric bypass plumbing arrangement.
If a filter is used, all gas must enter the instrument through the filter.
Note The calibration and calibration check duration times should be long
enough to account for the transition (purge) process when switching from
sample to zero and from zero to span. This transition time is the time
required to purge the existing air. ▲
Depending on the plumbing configuration and the instrument, data from
approximately the first minute of a zero calibration or check should be
disregarded because of residual sample air. Also, data from approximately
the first minute of a span calibration or check should be disregarded
because the span is mixing with the residual zero air. ▲
Use the following procedure to perform a zero/span calibration.
1. If the instrument is equipped with the optional zero/span and sample
valves, connect the zero and span gas to the rear panel bulkheads
labeled ZERO IN and SPAN, otherwise connect a source of vented
zero air to the SAMPLE bulkhead. The top right of the title bar
indicates which mode is active: ZERO, SPAN, or SAMPLE.
Note Do not use nitrogen for zero air.
▲
2. To ensure that the zero air is being measured at atmospheric pressure,
check that the zero air flow reported by the analyzer is approximately
0.5 LPM. Actual zero air flow should be 0.8 LPM or more, with the
excess flowing out the atmospheric bypass.
a. From the Home screen choose Settings>Health Check>Status
and Alarms>Flow and Pressure.
b. Make sure that the reported sample flow is less than the actual zero
air flow.

Regulations typically require zero/span calibration when the instrument is
newly installed, moved, repaired, interrupted for more than a few days, or
when span or zero shift by more than 15%.
All gas must be supplied to the instrument at atmospheric pressure. It may
be necessary to employ an atmospheric bypass plumbing arrangement to
accomplish this. Refer to Figure 2–6 in the “Installation and Setup” chapter
for an example of an atmospheric bypass plumbing arrangement.
If a filter is used, all gas must enter the instrument through the filter.
Note The calibration and calibration check duration times should be long
enough to account for the transition (purge) process when switching from
sample to zero and from zero to span. This transition time is the time
required to purge the existing air. ▲
Depending on the plumbing configuration and the instrument, data from
approximately the first minute of a zero calibration or check should be
disregarded because of residual sample air. Also, data from approximately
the first minute of a span calibration or check should be disregarded
because the span is mixing with the residual zero air. ▲
Use the following procedure to perform a zero/span calibration.
1. If the instrument is equipped with the optional zero/span and sample
valves, connect the zero and span gas to the rear panel bulkheads
labeled ZERO IN and SPAN, otherwise connect a source of vented
zero air to the SAMPLE bulkhead. The top right of the title bar
indicates which mode is active: Zero, Span, or Sample.
Note Do not use nitrogen for zero air.

Zero and Span
Check
The zero and span check procedure is normally performed any time a quick
check of the accuracy of the instrument is required. Normally, zero and
span are checked daily. As experience is gained with the instrument, the
frequency of these checks can be adjusted accordingly.
The span gas concentration used in the span check should be between 70%
and 90% of the full-scale range. The zero and span drift should be
measured and recorded prior to making any adjustments.
All gas must be supplied to the instrument at atmospheric pressure. It will
be necessary to employ an atmospheric bypass plumbing arrangement to
accomplish this.
If a filter is used, all gas must enter the instrument through the filter.
Use the following procedure to check the zero/span.
1. If the instrument is equipped with the optional zero/span and sample
valves, connect the zero and span gas to the rear panel bulkheads
labeled ZERO IN and SPAN, otherwise connect a source of vented
zero air to the SAMPLE bulkhead.
Note Do not use nitrogen for zero air.

recommended that a new calibration be performed.
5. Connect a source of vented span gas to the SAMPLE bulkhead. The
span gas should be approximately 80% of the full-scale range.
6. To ensure that the span gas is being measured at atmospheric pressure
check that the flow is approximately 0.5 LPM or more, with the excess

8. Record the difference between the measured SO2 value and the actual
SO2 span concentration used. This is the span drift since the last
adjustment. If the calibration has changed by more than ±10%, a new
calibration should be performed.
Manual
Calibration
The Manual Calibration screen allows the user to view and manually adjust
the zero background and span coefficient. These are used to correct the
SO2 readings that the instrument generates using its own internal
calibration data.
Normally, the zero background and span coefficient are calculated
automatically at the Calibrate Background and Calibrate Span Coefficient
described earlier in the chapter. However, the calibration factors can also be
set manually using the functions as described below.
The following screen is shown in single range mode. In dual or auto range
modes, “High Range” or “Low Range” buttons are displayed to indicate the
calibration of the high or low coefficient. The Adjust High Range Span

same way as the zero duration button. The span duration button is used to
set how long the span gas is sampled by the instrument. The purge
duration button is used to set how long the purge period will be after doing
a zero and/or span. This gives the instrument time to flush out the zero and
span gas before any meaningful sample data is taken. Logged data is flagged
as taken during a purge to show that the data is suspect. Durations between
0 and 99 minutes are acceptable. Each time a zero/span schedule occurs the
zero is done first, followed by the span. To perform just a zero, set the span
duration to 0 (off). The same applies to perform just a span.

Background Calibration and Span Calibration are toggle buttons that
change between enabled or disabled.
If the background calibration is set to enabled, then a zero adjustment is
made. If the span calibration is set to enabled, then a span adjustment is
made. (This is how to set up a scheduled, recurring auto calibration.)
The Zero/Span Ratio button is used to set the ratio of zero checks or
adjustments to span checks or adjustments. For example, if this value is set
to 1, a span duration will follow every zero duration. If this value is set to 3,
there will be two zero checks between each span check. This value may be
set from 1 to 99, with 1 as default.

The 43iQ deploys a set of modular subsystems that comprise the total
instrument function. The core measurements for concentration are
contained in Distributed Measurement and Control (DMC) modules. This

43iQ Instruction Manual 8-1
System Description
Optical Bench DMC
●
Optical Bench
DMC
The Optical Bench DMC contains the key components of the optical
measurement that eventually results in SO2 concentration. In the reaction
chamber pulsating light from the flash lamp excites the SO2 molecules. A
condenser lens collects and focuses light from fluorescing SO2 molecules
onto the PMT assembly.
Heated Hydrocarbon
Kicker
The heated hydrocarbon kicker removes hydrocarbons from the gas stream
while leaving the SO2 concentration unaffected. It operates on a selective
permeation principle using differential pressure to force hydrocarbon
molecules to pass through the tube wall. The differential pressure is created
across the tube wall as sample gas passes through a capillary tube which
reduces its pressure. The sample gas is then fed to the shell side of the
hydrocarbon kicker. The heated kicker operates at the same temperature as
the optical bench and requires no additional power.
Optical Bench
Hardware
The optics section provides the light source for the fluorescence reaction
and optimizes the reaction with a system of lenses and mirrors. It includes a
flash lamp, condensing lens, bandpass mirror assembly and light baffle.
Condensing Lens
The condensing lens focuses light from the flash lamp into the mirror
assembly.
Mirror Assembly
A set of four mirrors selectively reflects only those wavelengths used in
exciting SO2 molecules. This reflective filtering causes the radiation
reaching the detection chamber to be more intense and more stable
throughout the lifetime of the instrument.
Light Baffle
Bandpass Filter
8-2
Firmware
43iQ Instruction Manual
The circular baffle helps keep stray light from entering the detection
volume.
The bandpass filter restricts the light reaching the photomultiplier tube to
the SO2 fluorescence wavelengths.
Thermo Scientific
System Description
Optical Bench DMC
Flash Lamp Trigger
Assembly
The flash lamp trigger assembly pulses the UV flash lamp at a rate of 10
times per second for improved signal-to-noise ratio and long term stability.
The lamp is operated in the pulsed mode for six major reasons:
Flash Lamp
Flash Trigger Board
●
Long life
●
High optical intensity – improved signal to noise ratio
●
Small size
●
Low power requirements – less than 1 watt
●
Long-term stability
●
Chopped signal processing – no dark current drift
The flash lamp provides the ultraviolet light source that causes the
fluorescence reaction in the SO2 molecules.
The flash trigger board is located in the base of the flash lamp assembly. It
receives high voltage and the trigger signal from the measurement interface
board and uses a small transformer to produce a short, high-voltage pulse to
fire the flash lamp.
Flash Intensity Assembly
The flash intensity assembly is located in the fluorescence chamber and
continuously monitors the pulsating UV flash lamp. This photodetector is
connected to a circuit that automatically compensates for fluctuations in
flash lamp output.
Photomultiplier
Tube
The PMT power supply produces high voltage to operate the
photomultiplier tube used in the measurement system. The output voltage
is adjustable from approximately 600 to 1200 volts under software control.
The PMT converts optical energy from the reaction to an electrical signal.
This signal is sent to the input board which transmits it to the processor.
Optical Bench DMC
Board
The optical bench DMC board accepts the current signal from the PMT
and converts it to a voltage, which is scaled by a factor of approximately 1,
10, or 100 depending on the full-scale range of the SO2 channel.
Thermo Scientific
43iQ Instruction Manual
8-3
System Description
Permeation Oven (Optional)
Bench Heater
The fluorescence chamber temperature is measured with a thermistor. The
voltage across the thermistor is fed to the main processor for use in
calculating and displaying the reaction chamber temperature. The voltage
across the thermistor is also compared to a set-point voltage and used to
control that the reaction chamber heaters to maintain a constant
temperature.
Permeation Oven
(Optional)
The 43iQ can be configured with an optional permeation oven for
generating SO2 span gas. The permeation oven is configured as a DMC
module with self-contained temperature measurements and heater controls.
For more information, see “Internal Permeation Span Source” as described
in Chapter 9, “Optional Equipment”.
Common
Electronics
The common electronics contain the core computational and power

Power Supply
Front Panel
I/O and
Communication
Components
All electronics operate from a universal VDC supply, which is capable of
auto-sensing the input voltage and working over all specified operating
ranges. The 43iQ contains a 24 VDC channel for most electronics
operation, including the pump and fan, and a 48 VDC channel dedicated
specifically for optical bench heating.
Front panel electronic components include the touch screen display, the on
off switch, and two indicator LEDs for power and alarm status, as
described in operational detail in Chapter 2, “Installation and Setup”.
The iQ series instruments provide a number of methods for
communicating the instrument results to the operator or external
equipment. Every iQ series instrument includes a front panel display, 2
USB ports, and one Ethernet data port as standard equipment.
In addition, optional RS-232/485, analog I/O, and digital I/O ports are
available to provide data to external systems as described in Chapter 9,
“Optional Equipment”. The front panel GUI allows the operator to
configure these output communication channels as described in Chapter 3,
“Operation”.
System Controller
Board
The System Controller Board (SCB) contains the main processor, power
supplies, and a sub-processor, and serves as the communication hub for the
instrument. The SCB receives operator inputs from the front panel GUI
and/or over optional I/O connections on the rear panel. The SCB sends
commands to the other boards to control the functions of the instrument
and to collect measurement and diagnostic information. The SCB outputs
instrument status and measurement data to the GUI, Ethernet/USB, and
to the optional rear-panel I/O. The SCB plugs into the backplane via a
single connector and has physical retainers to secure placement.
Backplane Board
The backplane board provides the routing and conditioning for +24 VDC
(optional +48 VDC) and RS-485 communications within the instrument.
It hosts the System Controller Board (SCB) and Peripherals Support Board
(PSB) via direct plug ins, and similarly hosts optional I/O (communication,
analog, and digital) with rear panel interfaces via direct plug in. It has
connections for RS485 communication with and powering of DMCs and
the STEP POL Module. It additionally routes the front panel display and
driver, external USB and Ethernet.

The STEP POL board provides high/low outputs for continuous operation
or on/off states. The STEP POL board contains the basic circuitry to
provide a programmable load to passive devices, either continuously, or on
user or automated command. In the iQ Series instruments, the pump,
solenoids, etc., are controlled off of the STEP POL board from commands
generated via the PSB.
Internal vacuum pump for generating air/sample through the instrument
Optional solenoid valves for switching between sample, zero, and span
gases, and other optional components.
The Flow/Pressure DMC is used measure instrument pressures that assure
proper flow regulation and for sample pressure within the measurement
bench for pressure corrections and compensation.
The DMC includes two pressure sensors that read 0-860 mmHg. These
sensors are used with the coupled restricting capillary for flow control along
with the downstream sample pump. The pressure differential determines
the flow through the capillary. The upstream pressure is the measurement
bench pressure, while the downstream pressure is at the pump inlet
pressure.
Firmware

43iQ Instruction Manual
Like the hardware, the firmware is modular and located within
microprocessors distributed throughout the instrument. In the 43iQ,
microprocessors containing firmware are located as follows:
●
Optical Bench DMC
●
Flow/Pressure DMC
●
Peripherals Support Board
●
Optional I/O (Communications, Digital, and Analog)
Thermo Scientific
System Description
Firmware
●
Optional Permeation Oven
The firmware contains the active controls for their application, as well as
self-identification and configuration for “plug and play” style operation.
Each are associated with specific registers of two types:
●
Modbus registers that are communicated from each microprocessor to
the System Controller Board (SCB) via internal RS-485
●
SNMP registers that are maintained in the software and SCB for health
and data processing computation
The Modbus communication system operates on 1 second intervals.
Within those intervals, data treatment like integration (whether analog or
digital) and servo control, are embedded in the module firmware. The SCB
receives the 1 second updates for higher level “software” processing and
control via SNMP registers, some of which is interfaced with the front
panel Graphical User Interface (GUI).
In addition to the operating registers, the 43iQ stores a historical data log
in a MySQL database. The memory is provided on the same μSD card
where the operating software resides, for which there is capability to store
up to a year of data at 1 minute intervals. Chapter 3, “Operation” describes
how this database is accessed and used including external memory
downloads.

Internal Zero/Span and Sample Valves
Internal Zero/Span
and Sample Valves
With the zero/span assembly option, a source of span gas is connected to
the SPAN port and a source of zero air is connected to the ZERO IN port.
It may be necessary to use an atmospheric dump bypass plumbing
arrangement to accomplish this.
For more information, refer to the “Installation and Setup” chapter and the
“Operation” chapter.
Internal
Permeation Span
Source
The Internal Permeation Span Source option is designed to provide a
simple span check. This option is intended as a quick, convenient check to
be used between zero and span calibrations for determining instrument
malfunction or drift. Because this option does not precisely control dilution
gas flow, it should not be used as a basis for instrument zero and span
adjustments, calibration updates or adjustment of ambient data.
Whenever there is an indication of possible instrument drift or
malfunction, a full zero and calibration (Level 1) should be performed prior
to corrective action. For further information on zero, span and calibration
of air pollution monitors, refer to Section 2.0.9 of the US EPA's Quality
Assurance Handbook for Air Pollution Measurement Systems (Volume II).
Figure 9–9 shows how this option is integrated with the 43iQ components.
During normal operation, the pump draws zero air through the permeation
oven and out the instrument exhaust. When performing a single point span
check, the sample valve is energized, closing the sample valve, and the Perm
valve is energized, opening the perm valve. This directs the zero air/SO2 gas
mixture from the permeation oven gas through the heated hydrocarbon
kicker and into the optical bench.

Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.
BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE,
THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT
PERMITTED BY APPLICABLE LAW.
The Open Source code used in the development of this product will be

[This is the first released version of the Lesser GPL. It also counts as the
successor of the GNU Library Public License, version 2, hence the version
number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to
share and change it. By contrast, the GNU General Public Licenses are
intended to guarantee your freedom to share and change free software--to
make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially
designated software packages--typically libraries--of the Free Software
Foundation and other authors who decide to use it. You can use it too, but
we suggest you first think carefully about whether this license or the
ordinary General Public License is the better strategy to use in any
particular case, based on the explanations below.
When we speak of free software, we are referring to freedom of use, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for this
service if you wish); that you receive source code or can get it if you want it;
Thermo Scientific
43iQ Instruction Manual
C-1
GNU Lesser General Public License
GNU Lesser General Public License
that you can change the software and use pieces of it in new free programs;
and that you are informed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors
to deny you these rights or to ask you to surrender these rights. These
restrictions translate to certain responsibilities for you if you distribute
copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a
fee, you must give the recipients all the rights that we gave you. You must
make sure that they, too, receive or can get the source code. If you link
other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making
changes to the library and recompiling it. And you must show them these
terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the
library, and (2) we offer you this license, which gives you legal permission
to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no
warranty for the free library. Also, if the library is modified by someone
else and passed on, the recipients should know that what they have is not
the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free
program. We wish to make sure that a company cannot effectively restrict
the users of a free program by obtaining a restrictive license from a patent
holder. Therefore, we insist that any patent license obtained for a version
of the library must be consistent with the full freedom of use specified in
this license.
Most GNU software, including some libraries, is covered by the ordinary
GNU General Public License. This license, the GNU Lesser General
Public License, applies to certain designated libraries, and is quite different
from the ordinary General Public License. We use this license for certain
libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a
shared library, the combination of the two is legally speaking a combined
work, a derivative of the original library. The ordinary General Public
License therefore permits such linking only if the entire combination fits its
criteria of freedom. The Lesser General Public License permits more lax
criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does Less
to protect the user's freedom than the ordinary General Public License. It
also provides other free software developers Less of an advantage over
competing non-free programs. These disadvantages are the reason we use
C-2
43iQ Instruction Manual
Thermo Scientific
GNU Lesser General Public License
GNU Lesser General Public License
the ordinary General Public License for many libraries. However, the
Lesser license provides advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage
the widest possible use of a certain library, so that it becomes a de-facto
standard. To achieve this, non-free programs must be allowed to use the
library. A more frequent case is that a free library does the same job as
widely used non-free libraries. In this case, there is little to gain by limiting
the free library to free software only, so we use the Lesser General Public
License.
In other cases, permission to use a particular library in non-free programs
enables a greater number of people to use a large body of free software. For
example, permission to use the GNU C Library in non-free programs
enables many more people to use the whole GNU operating system, as well
as its variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users'
freedom, it does ensure that the user of a program that is linked with the
Library has the freedom and the wherewithal to run that program using a
modified version of the Library.
The precise terms and conditions for copying, distribution and
modification follow. Pay close attention to the difference between a "work
based on the library" and a "work that uses the library". The former
contains code derived from the library, whereas the latter must be
combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE TERMS AND
CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFICATION
0. This License Agreement applies to any software library or other program
which contains a notice placed by the copyright holder or other authorized
party saying it may be distributed under the terms of this Lesser General
Public License (also called "this License"). Each licensee is addressed as
"you".
A "library" means a collection of software functions and/or data prepared
so as to be conveniently linked with application programs (which use some
of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has
been distributed under these terms. A "work based on the Library" means
either the Library or any derivative work under copyright law: that is to say,
a work containing the Library or a portion of it, either verbatim or with
modifications and/or translated straightforwardly into another language.
(Hereinafter, translation is included without limitation in the term
"modification".)
Thermo Scientific
43iQ Instruction Manual
C-3
GNU Lesser General Public License
GNU Lesser General Public License
"Source code" for a work means the preferred form of the work for making
modifications to it. For a library, complete source code means all the
source code for all modules it contains, plus any associated interface
definition files, plus the scripts used to control compilation and installation
of the library.
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of running a
program using the Library is not restricted, and output from such a
program is covered only if its contents constitute a work based on the
Library (independent of the use of the Library in a tool for writing it).
Whether that is true depends on what the Library does and what the
program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices that
refer to this License and to the absence of any warranty; and distribute a
copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you
may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it,
thus forming a work based on the Library, and copy and distribute such
modifications or work under the terms of Section 1 above, provided that
you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
that you changed the files and the date of any change.
stating
c) You must cause the whole of the work to be licensed at no charge to all
third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of data
to be supplied by an application program that uses the facility, other than
as an argument passed when the facility is invoked, then you must make a
good faith effort to ensure that, in the event an application does not supply
such function or table, the facility still operates, and performs whatever part
of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose
that is entirely well-defined independent of the application. Therefore,
Subsection 2d requires that any application-supplied function or table used
by this function must be optional: if the application does not supply it, the
square root function must still compute square roots.)
C-4
43iQ Instruction Manual
Thermo Scientific
GNU Lesser General Public License
GNU Lesser General Public License
These requirements apply to the modified work as a whole. If identifiable
sections of that work are not derived from the Library, and can be
reasonably considered independent and separate works in themselves, then
this License, and its terms, do not apply to those sections when you
distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Library, the
distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to each
and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based on
the Library.
In addition, mere aggregation of another work not based on the Library
with the Library (or with a work based on the Library) on a volume of a
storage or distribution medium does not bring the other work under the
scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public
License instead of this License to a given copy of the Library. To do this,
you must alter all the notices that refer to this License, so that they refer to
the ordinary GNU General Public License, version 2, instead of to this
License. (If a newer version than version 2 of the ordinary GNU General
Public License has appeared, then you can specify that version instead if
you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so
the ordinary GNU General Public License applies to all subsequent copies
and derivative works made from that copy. This option is useful when you
wish to copy part of the code of the Library into a program that is not a
library.
4. You may copy and distribute the Library (or a portion or derivative of it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you accompany it with the complete
corresponding machine-readable source code, which must be distributed
under the terms of Sections 1 and 2 above on a medium customarily used
for software interchange.
If distribution of object code is made by offering access to copy from a
designated place, then offering equivalent access to copy the source code
from the same place satisfies the requirement to distribute the source code,
even though third parties are not compelled to copy the source along with
the object code.
5. A program that contains no derivative of any portion of the Library, but
is designed to work with the Library by being compiled or linked with it, is
Thermo Scientific
43iQ Instruction Manual
C-5
GNU Lesser General Public License
GNU Lesser General Public License
called a "work that uses the Library". Such a work, in isolation, is not a
derivative work of the Library, and therefore falls outside the scope of this
License.
However, linking a "work that uses the Library" with the Library creates an
executable that is a derivative of the Library (because it contains portions of
the Library), rather than a "work that uses the library". The executable is
therefore covered by this License. Section 6 states terms for distribution of
such executables.
When a "work that uses the Library" uses material from a header file that is
part of the Library, the object code for the work may be a derivative work
of the Library even though the source code is not. Whether this is true is
especially significant if the work can be linked without the Library, or if the
work is itself a library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data structure layouts
and accessors, and small macros and small inline functions (ten lines or less
in length), then the use of the object file is unrestricted, regardless of
whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the
object code for the work under the terms of Section 6. Any executables
containing that work also fall under Section 6, whether or not they are
linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a
"work that uses the Library" with the Library to produce a work containing
portions of the Library, and distribute that work under terms of your
choice, provided that the terms permit modification of the work for the
customer's own use and reverse engineering for debugging such
modifications.
You must give prominent notice with each copy of the work that the
Library is used in it and that the Library and its use are covered by this
License. You must supply a copy of this License. If the work during
execution displays copyright notices, you must include the copyright notice
for the Library among them, as well as a reference directing the user to the
copy of this License. Also, you must do one of these things:
a) Accompany the work with the complete corresponding machinereadable source code for the Library including whatever changes were used
in the work (which must be distributed under Sections 1 and 2 above);
and, if the work is an executable linked with the Library, with the complete
machine-readable "work that uses the Library", as object code and/or
source code, so that the user can modify the Library and then relink to
produce a modified executable containing the modified Library. (It is
C-6
43iQ Instruction Manual
Thermo Scientific
GNU Lesser General Public License
GNU Lesser General Public License
understood that the user who changes the contents of definitions files in
the Library will not necessarily be able to recompile the application to use
the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A
suitable mechanism is one that (1) uses at run time a copy of the library
already present on the user's computer system, rather than copying library
functions into the executable, and (2) will operate properly with a modified
version of the library, if the user installs one, as long as the modified version
is interface-compatible with the version that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to
give the same user the materials specified in Subsection 6a, above, for a
charge no more than the cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a
designated place, offer equivalent access to copy the above specified
materials from the same place.
e) Verify that the user has already received a copy of these materials or that
you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library"
must include any data and utility programs needed for reproducing the
executable from it. However, as a special exception, the materials to be
distributed need not include anything that is normally distributed (in either
source or binary form) with the major components (compiler, kernel, and
so on) of the operating system on which the executable runs, unless that
component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of
other proprietary libraries that do not normally accompany the operating
system. Such a contradiction means you cannot use both them and the
Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library sideby-side in a single library together with other library facilities not covered
by this License, and distribute such a combined library, provided that the
separate distribution of the work based on the Library and of the other
library facilities is otherwise permitted, and provided that you do these two
things:
a) Accompany the combined library with a copy of the same work based on
the Library, uncombined with any other library facilities. This must be
distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of
it is a work based on the Library, and explaining where to find the
accompanying uncombined form of the same work.

8. You may not copy, modify, sublicense, link with, or distribute the
Library except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense, link with, or distribute the Library is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such parties
remain in full compliance.
9. You are not required to accept this License, since you have not signed it.
However, nothing else grants you permission to modify or distribute the
Library or its derivative works. These actions are prohibited by law if you
do not accept this License. Therefore, by modifying or distributing the
Library (or any work based on the Library), you indicate your acceptance of
this License to do so, and all its terms and conditions for copying,
distributing or modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the
Library), the recipient automatically receives a license from the original
licensor to copy, distribute, link with or modify the Library subject to these
terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein. You are not responsible for
enforcing compliance by third parties with this License.
11. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not excuse
you from the conditions of this License. If you cannot distribute so as to
satisfy simultaneously your obligations under this License and any other
pertinent obligations, then as a consequence you may not distribute the
Library at all. For example, if a patent license would not permit royaltyfree redistribution of the Library by all those who receive copies directly or
indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any
particular circumstance, the balance of the section is intended to apply, and
the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or
other property right claims or to contest validity of any such claims; this
section has the sole purpose of protecting the integrity of the free software
distribution system which is implemented by public license practices.
Many people have made generous contributions to the wide range of
software distributed through that system in reliance on consistent
application of that system; it is up to the author/donor to decide if he or
she is willing to distribute software through any other system and a licensee
cannot impose that choice.

GNU Lesser General Public License
This section is intended to make thoroughly clear what is believed to be a
consequence of the rest of this License.
12. If the distribution and/or use of the Library is restricted in certain
countries either by patents or by copyrighted interfaces, the original
copyright holder who places the Library under this License may add an
explicit geographical distribution limitation excluding those countries, so
that distribution is permitted only in or among countries not thus
excluded. In such case, this License incorporates the limitation as if written
in the body of this License.
13. The Free Software Foundation may publish revised and/or new
versions of the Lesser General Public License from time to time. Such new
versions will be similar in spirit to the present version, but may differ in
detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library
specifies a version number of this License which applies to it and "any later
version", you have the option of following the terms and conditions either
of that version or of any later version published by the Free Software
Foundation. If the Library does not specify a license version number, you
may choose any version ever published by the Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs
whose distribution conditions are incompatible with these, write to the
author to ask for permission. For software which is copyrighted by the

How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible
use to the public, we recommend making it free software that everyone can
redistribute and change. You can do so by permitting redistribution under
these terms (or, alternatively, under the terms of the ordinary General
Public License).
To apply these terms, attach the following notices to the library. It is safest
to attach them to the start of each source file to most effectively convey the
exclusion of warranty; and each file should have at least the "copyright" line
and a pointer to where the full notice is found.
Copyright (C)
This library is free software; you can redistribute it and/or modify it under
the terms of the GNU Lesser General Public License as published by the
Free Software Foundation; either version 2.1 of the License, or (at your
option) any later version.
This library is distributed in the hope that it will be useful, but
WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
See the GNU Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public License
along with this library; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the library, if necessary.
Here is a sample; alter the names:

As an additional permission to the GNU Lesser General Public License
version 2.1, the object code form of a ""work that uses the Library"" may

structure layouts, accessors, macros, inline functions and templates; and
(iii) you comply with the terms of Section 6 of the GNU Lesser General
Public License version 2.1.
Moreover, you may apply this exception to a modified version of the

material is limited to (i) numerical parameters; (ii) data structure layouts;
(iii) accessors; and (iv) small macros, templates and inline functions of five
