SS2100i gas analyzers accurately measure trace gas components (H2O, CO2, H2S, NH3, and C2H2) using tunable diode laser absorption spectroscopy (TDLAS) technology. The analyzers require little maintenance and do not need recalibration or periodic replacement parts. SS2100i gas analyzers are certified for ATEX/IECEx Zone 1.
Gas analysis: ppb level measurement of H2O & NH3, ppm level measurement of H2O, H2S, CO2, NH3, and C2H2, and % level measurement of H2S and CO2
Natural gas: production, storage, transportation, distribution
Check out the findings from the GERG report on the use of a Raman Rxn4 analyzer and Raman Rxn-41 cryogenic probe for the reliable chemical composition measurement in LNG custody transfer applications.
