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.
