Chapter 1
Introduction
The Thermo Scientific™ 43iQ Trace Level SO2Analyzer utilizes pulsed
fluorescence technology to measure the amount of sulfur dioxide in the air
to .05 ppb.
The 43iQTL operates on the principle that the pulsing of the U.V. source
lamp serves to increase the optical intensity whereby a greater U.V. energy
throughput and lower detectable SO2concentration are realized.
Reflective bandpass filters, as compared to commonly used transmission
filters, are less subject to photochemical degradation and more selective in
wavelength isolation. A wide variety of internal diagnostics, with user
settable alarm levels, are available from an easy to follow touch screen
menu. This results in both increased detection specificity and long term
stability.
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
experience to simplify daily operations. Custom designed ePort
software allows remote access to the analyzer with a PC. The ePort
control mirrors the same GUI look and feel as the instrument
touchscreen providing a speedy and familiar operational experience.

Introduction
43iQTL Principle of Operation
Thermo Scientific 43iQTL Instruction Manual 1-3
The 43iQTL operates on the principle that SO2molecules 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,
22212
hSO*SOhSO υυ +→→+
The sample is drawn into the 43iQTL 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 SO2molecules pass
through the hydrocarbon “kicker” unaffected. The sample then flows into
the fluorescence chamber. Pulsating UV light is focused by a condensing
lens into the mirror assembly. The mirror assembly contains eight selective
mirrors that reflect only the wavelengths which excite SO2molecules. The
pulsating UV light excites the SO2molecules in the fluorescence chamber.
A 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 excited SO2molecules decay to lower energy states they emit UV
light that is proportional to the SO2concentration. The bandpass filter
allows only the wavelengths emitted by the excited SO2molecules to reach
the photomultiplier tube (PMT). The PMT detects the UV light emission
from the decaying SO2molecules.
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 43iQTL outputs the SO2concentration to the front panel
display and the analog outputs, and also makes the data available over the
serial or Ethernet connection.
