Using patented tunable diode laser absorption spectroscopy (TDLAS) technology, the SS2100 gas analyzer measures specific gases (H2O, CO2, and H2S) with precision while avoiding interferences that are common with traditional infrared analyzers. The SS2100 analyzer requires little maintenance and does not need recalibration or periodic replacement parts.
Gas analysis: ppb level measurement of H2O, ppm level measurement of H2O, H2S, and CO2, and percent (%) level measurement of H2S and CO2
Natural gas: production, storage, transportation, distribution
Borealis is monitoring of polypropylene and polyethylene grades during olefin polymerization reactions in continuously fed loop reactors in the Chemical Industry.
An advanced gas analyzer for hydrogen sulfide (H2S) measurement. The SS2100 uses tunable diode laser absorption spectroscopy (TDLAS) to determine the concentration of the analyte without coming into physical contact with the stream.
