The G-CEM4100 is a hot extractive analyzer using infrared absorption spectroscopy to measure up to seven gases in a single self-contained chamber unit. The conventional extractive systems require sampled gases to be cleaned and dried to a very high purity prior to analysis invariably resulting in a elaborate sampling system requiring high maintenance. Model G-CEM4100 draws gases through a coarse filter probe and transports to the measurement chamber via a short heated sample hose-without elaborate conditioning.
Multiple gases in one Analyzer
Minimal sampling required
Suitable for mass emissions analysis
Fully compliant to 40CFR60 and 75
Remote MODEM/Web access
No chillers, pumps or sampling system required
Most suitable for analysis of water soluble gases by hot-wet technique like ammonia
Water vapor also measured to compensate for true EPA Mass emissions data
Low cost NDIR on-stack continuous monitoring for 7 gases in one analyzer most suitable high temperature process or flue gas
Simple installation with only ONE module, NEMA 4X Analyzer and sample and Cal gas connections
Summary Specification
Measurements
Main measurement channels (1-7): Any combination of up to seven gases from CO/CO2 /NO/NO2 /SO2 /HCl/UHC/H2 O
Measurement Limits (maximum): CO2 /H2 O 50% (vol); SO2 50000 ppm (vol) Others 6000 ppm (vol)
Measurement Spans: CO/NO/NO2 /SO2 /HCl/UHC selectable up to 9,999vpm; CO2 /H2 O selectable up to 99%
Note that although very low spans can be configured, this should not be done without consideration of the measurement uncertainty.
