The inlet gas line is configured to pressurize an input end of a column and to deliver a split or purge flow. The conduit assembly includes a conduit surrounding the input end of the analytical column and coupled to a carrier gas line and a controller. The inlet gas line and the carrier gas line connect to a common gas source. The controller, connected to the conduit, has a first mode delivering a flow of carrier gas which is less than the column flow during an injection period to effect a sample transfer to the column and a second mode delivering a flow of carrier gas greater than the column flow following an injection period to prevent the split or purge flow from entering the column."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Carrier gas reduction for gas chromatography","description":"A device for a gas chromatograph (GC) system includes an injector connected to an inlet gas line and a conduit assembly.
