Continuous emission monitoring system (CEMS)
GCEM4100 Codel International

The GCEM4100 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 high maintenance costs. Such elaborate pre-conditioning is not required by the GCEM4100. Process gases are continuously drawn through a fine filtered probe installed in the flue gas and transported to the measurement chamber via a heated sample line - without further conditioning. Designed for use on gas turbines, the analyser is MCERTS certified and satisfies QAL1 of the EU Standard EN14181 for LCPD emission limit values above 40ppm.
