Introduction
The Thermo Scientific™ 49iQ Ozone Primary Standard utilizes UV
Photometric technology to reliably produce ozone up to 1000 ppb in
concentration.
The 49iQ Ozone Primary Standard is a dual cell photometer, the concept
adopted by NIST for the national ozone standard. The instrument can
accurately generate up to 1000 ppb of ozone operating with ozonator flow
rates between 3-4 liters per minute. Because the instrument has both
sample and reference flowing simultaneously, a response time of 20 seconds
can be achieved. Temperature and pressure correction are standard
offerings.
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 instrument
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
iQ Series

experience to simplify daily operations. Custom designed ePort
software allows remote access to the instrument 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
Principle of Operation
Thermo Scientific 49iQPS Instruction Manual 1-3
The 49iQPS operates on the principle that ozone (O3) molecules absorb
UV light at a wavelength of 254 nm. The degree to which the UV light is
absorbed is directly related to the ozone concentration as described by the
Beer-Lambert Law:
KLC
e
o
I
I
where:
K = molecular absorption coefficient, 308 cm-1 (at 0°C and 1
atmosphere)
L = length of cell, 38 cm
C = ozone concentration in parts per million (ppm)
I = UV light intensity of sample with ozone (sample gas)
Io= UV light intensity of sample without ozone (reference gas)
Zero air is supplied to the 49iQPS through the zero air bulkhead and is
split into two gas streams, as shown in Figure 1–2. One gas stream flows
through a pressure regulator to the reference solenoid valve to become the
reference gas (Io). The second zero air stream flows through a pressure
regulator, ozonator, and manifold to the sample solenoid valve to become
the sample gas (I). Ozone from the manifold is delivered to the ozone
bulkhead. The solenoid valves alternate the reference and sample gas
streams between cells A and B every 10 seconds. When cell A contains
reference gas, cell B contains sample gas and vice versa.
The UV light intensities of each cell are measured by detectors A and B.
When the solenoid valves switch the reference and sample gas streams to
opposite cells, the light intensities are ignored for several seconds to allow
the cell to be flushed. The 49iQPS calculates the ozone concentration for
each cell and outputs the average concentration to the front panel display,
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.
Equipment Damage Do not attempt to lift the instrument by the cover or
other external fittings. ▲
The 49iQPS 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–
1” on page 2-2.)
3. Check for possible damage during shipment.
4. Check that all connectors and circuit boards are firmly attached.
5. Re-install the cover.
6. Remove any protective plastic material from the case exterior.
