Natural, refinery, landfill, sewage digester and other fuel gases contain volatile sulfur compounds such as hydrogen sulfide, carbonyl sulfide, and mercaptans that are corrosive, poisonous and subject to regulation. Municipal distribution of the methane fraction as fuel requires both production and distribution facilities to accurately determine sulfur content. Fuel gases are also feedstocks for polymer production where the catalysts involved are poisoned by sulfur compounds. Gas chromatography (GC) can be used for the determination of sulfur species but requires special detectors such as flame photometric (FPD), sulfur chemiluminescence (SCD) and pulsed flame photometric (PFPD). These detectors can suffer from hydrocarbon interference, operational complexity and non-linearity.View Resources
The G908 sulfur species analyzer integrates the speed and separating power of a ballistic gas chromatograph with our ultra-compact, low maintenance and rugged high pressure mass spectrometer (HPMS). In under 5-minutes, G908 separates and quantifies sulfphur compounds at low-ppm to ppb levels using HPMS total ion count (TIC) or selective ion monitoring (SIM), significantly increasing selectivity and sensitivity.
