Abstract:
1. A gas chromatography (GC) system comprising: a sample injector adapted to receive a liquid sample into an interior cavity thereof and to volatilize the liquid sample; a GC column configured to receive the volatilized sample from the sample injector, wherein the sample injector is configurable to perform either split injection or splitless injection into the GC column; a carrier gas inlet line fluidically coupled to a gas inlet port of the sample injector; a septum purge vent line fluidically coupled to a first gas outlet port of the sample injector; a split-flow vent line fluidically coupled to a second gas outlet port of the sample injector; and a vacuum system configured to place the septum purge vent line, the split-flow vent line and the interior cavity of the sample injector under vacuum.
