Arsine and phosphine in ethylene and propylene

The GAS arsine & phosphine in ethylene and propylene analyser is suitable for selective detection of very low concentration levels in various hydrocarbon samples. For more information about this analyser based on quadrupole MS detection, please download the application note. If you wish to speak with one of our employees, just give us a call.

Choose the arsine and phosphine analyser from GAS

Analysis of 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. 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 extreme separation power is used to separate the components of interest from the sample matrix. The GAS 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 H2S, COS and 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.
