ABSTRACT:
A gas chromatographic device comprises an inlet system and a chromatography column. The inlet system includes a liner having pressure reducing means contained therein for reducing pressure between an inlet of the pressure reducing means and an outlet of the pressure reducing means. When the devise is in use, the chromatography column is positioned in the liner of the inlet system downstream from the pressure reducing means, and the chromatography column is under vacuum at its outlet.
