An assembly for extracting analytes from a sample using a fluid under pressure, and embodying the invention, includes an extraction cell receiving the sample and having a chamber body closed at one end by a translatable slide block assembly in fluid communication with the fluid under pressure to introduce the fluid under pressure into the sample located within the chamber body; and a cylinder block assembly at the opposite end of the chamber body for extracting the fluid passing through the sample, the sample being enclosed in a vessel having a thimble body closed at opposite ends by pressure-fit end cap assemblies, each having a thimble cap, a seal, and a frit cap assembly for retaining the sample within the thimble body and permitting the passage of the fluid therethrough.

[ I claim:] [1.] An assembly for extracting analytes from a sample under pressure, comprising in combination:a vessel having a tubular housing, open at opposite ends, for retaining the sample under pressure; andan end cap assembly slidably received in an axial direction in each end of said vessel to close said vessel and help retain the sample therein, each end cap assembly including a cap having an axial bore extending therethrough with a first end received within said vessel, a frit disposed at said first end of said cap over said axial bore, and a gasket assembly intermediate said frit and an opposite end of said cap for sealing said end cap assembly within said vessel.
