Title: GAS CHROMATOGRAPH (GC) INLET LINER WITH PLUG OF BEADS
Abstract:
A liner for a gas chromatograph (GC) inlet includes a tube and a plug in the tube. The plug includes a plurality of closely packed spherical beads defining a plurality of tortuous fluid flow paths running through the plug. A sample and carrier gas may be flowed through the plug and into a GC column downstream from the liner. The liner, including the beads, may be heat to evaporate liquid droplets of the sample. The liner is compatible with use of a sample injection needle.
