GCEM4100 Extractive Multi-channel Gas Analyser0 pages

Extractive Flue Gas Analyser
The G-CEM4100 is a hot extractive analyser for
difficult flue gas monitoring applications. It uses
infrared absorption spectroscopy to measure up to
seven pollutant species in a single self-contained unit.
Many conventional extractive systems require the
sampled gas to be cleaned and dried to a very
high standard prior to analysis, invariably resulting
in a high maintenance demand. Such elaborate
pre-conditioning is not required; the G-CEM4100
creates ‘perfect’ duct conditions in a temperature
controlled chamber within a separate free-standing,
air-conditioned cabinet. Process gases are simply
cooled (or heated) then transferred along a heated
sample line, without further conditioning, to be
measured using a CODEL multi-channel analyser
housed in the cabinet.
Increasingly, environmental agencies demand that
continuous emission analysers have the facility to
prove their performance using known concentration
audit gases. The G-CEM4100 provides the facility
to automatically check and control zero using clean,
dry compressed air (or N2). Where independent span
checks are required, bottled gases of known
concentration can be injected directly into the
measurement chamber.
