Introduction
The Thermo Scientific™ 43iQ High Level SO2Analyzer utilizes pulsed
fluorescence technology to measure the amount of sulfur dioxide in the air
up to 1000 ppm in standard range and up to 10000 ppm in extended
range.
The 43iQHL 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
43iQHL Principle of Operation
Thermo Scientific 43iQHL Instruction Manual 1-3
The 43iQHL 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 43iQHL through the SAMPLE bulkhead, as
shown in Figure 1–2. The sample flows through the optional heated kicker
(if installed) and then into the into the fluorescence chamber. Pulsating UV
light is focused by a condensing lens into the mirror assembly. The mirror
assembly contains four selective mirrors that reflect only the wavelengths
which excite SO2molecules. The 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. A bandpass filter
located between the fluorescence chamber and PMT allows only the
wavelengths emitted by the decaying SO2molecules to reach the
photomultiplier tube (PMT). The PMT detects the UV light emission
from the decaying SO2molecules.
The sample exits the fluorescence chamber and flows through a capillary
and an auxiliary flow sensor. The sample then flows to the pump and is
exhausted out the EXHAUST bulkhead of the analyzer. The 43iQHL
outputs the SO2concentration to the front panel display and the analog
outputs, and also makes the data available over the serial or Ethernet
connection.

Installation and Setup
Installation and Setup describes how to unpack, setup, and start-up the
instrument. The installation should always be followed by instrument
calibration as described in the “Calibration” chapter of this manual.
Equipment Damage Do not attempt to lift the instrument by the cover or
other external fittings. ▲
The 43iQHL is shipped complete in one container. If there is obvious
damage to the shipping container when you receive the instrument, notify
the carrier immediately and hold for inspection. The carrier is responsible
for any damage incurred during shipment.
Use the following procedure to unpack and inspect the instrument.
1. Remove the instrument from the shipping container and set it on a
table or bench that allows easy access to both the front and rear.
2. Remove the cover to expose the internal components. (See “Figure 2–
