Introduction
System Overview
1-4 Omni FTIR Multi Gas CEMS Instruction Manual Thermo Fisher Scientific
The direct extractive probe assembly is used to extract and condition a
continuous sample from a stack or duct for transport to a gas analysis
system. The standard probe assembly consists of a 1-meter heated probe
barrel and pre-filter, a heated filter assembly, and a blow-back tank and
valve assembly. The standard sample probe has an ANSI 4-inch flange
mount and 1.0 meter heated probe barrel, but can be custom ordered to
meet customer requirements.
A flexible heated line is used to convey the sample from the sample probe
to the sample conditioning assembly in the system rack. This line includes
a 1/4-inch sample line, a 1/4-inch calibration line, and a 3/8-inch blowback
line. The sample line length may be from 33 feet (10 meters) to 100 feet
(30.5 meters).
The system includes a temperature control module which is used to control
the temperatures in the following components:
●
FTIR cell
●
Sample conditioning assembly
●
Heated lines to FTIR
●
Sample line
In addition, the FTIR cell pressure is measured with this controller.
The sample conditioning subsystem consists of multiple components that
are used to control and condition the sample and calibration gases:
●
Sample system heater assembly (pump, sample valve, check valve, pre-
heaters)
●
Hydrator
●
Pneumatic panel
●
FTIR purge gas generator
●
Instrument air filter assembly
The FTIR analyzer is a Thermo Scientific Antaris IGS instrument which is
based on a Michelson interferometer which measures the interaction of
infrared (IR) radiation with the sample. The FTIR analyzer includes a 5.2-
