ARS CS204-FMX-19-NGA Cryogenic Gas Trap for Noble Gas Analysis

The CS204E-FMX-19-NGA is a Cryogenic Gas Trap. This systems interfaces to the Mass Spectrometer line via a Swagelok or 1.33” Mini Conflat Flange. The system cools down a stainless steel canister (trap) that is either bare polished or containing activated charcoal. The cryogenic trap line is constructed for UHV environments and is made out of welded stainless steel.
