Choose the H2S, COS, arsine and phosphine analyser from GAS

Analysis of H2S, COS, arsine & phosphine below 1 ppb concentration level requires maximal effort of your analyser. The low detection limit that is offered by the ISQ 7000 GC-MS is driven down further by using the AEI (Advanced Election Impact) source. H2S, COS, arsine and phosphine easily adsorb to many materials; for this reason we use Restek Sulfinert®  treated parts to achieve a fully inert sample path. A capillary column with high separation power is used to separate the components of interest from the sample matrix. The H2S, COS, arsine & phosphine analyser based on GC-MS has an excellent reputation for this type of analysis, offering great sensitivity, selectivity and robustness. This instrument is also suitable for analysing other volatile sulphur components simultaneously. At GAS we aim for customer satisfaction. Providing not only the hardware, such as low sulphur and biogas analysers, but also a complete portfolio of services like; technical training, application support, demolab and training/courses.
