A system for the retrieval and initial conditioning of sample gas for "on line" analyzers or filling of gas sample cylinders. The preferred embodiment of the present invention contemplates a system configured to obtain a representative gas phase sample from a process gas containing entrained liquid, or a process gas which generally is highly susceptible to partial condensation of some gas phase components. The preferred embodiment of the present invention teaches an assembly including a phase separation membrane and housing configured to facilitate the removal of entrained liquid from a sample gas stream. Accuracy of the sample is enhanced, and compositional changes are avoided by first extracting a sample from the process gas followed by removal of entrained liquid it may contain, with the entrained liquid removal being conducted at the prevailing process gas pressure and temperature. Thereafter the liquid free sample may be desaturated by lowering its pressure to reduce its susceptibility to condensation.

1. A sample conditioning assembly for separation and removal of entrained liquid from gas in a fluid stream, comprising:an insertion assembly having a fluid conduit having first and second ends; a housing having first and second ends, said housing further formed to receive said insertion assembly; a phase separation membrane situated in association with said insertion assembly, said phase separation membrane having first and second sides, said phase separation membrane configured to allow the passage of gas therethrough, while coalescing entrained liquid from said gas, so as to provide filtered gas from said second side of said phase separation membrane, while providing coalesced liquid at said first side of said phase separation membrane; a valve, said valve formed to open when said insertion assembly is inserted into said housing so as to allow the migration of gas from said fluid stream to said first side of said phase separation membrane, said valve configured to close when said insertion assembly is removed from said housing.
