The gas chromatograph is composed of different elements: the injection chamber, a chromatographic column and a detector. The compounds are driven through these three elements with a stream of gas, called the carrier gas, which may hydrogen, nitrogen or a rare gas such as helium or argon... Gas chromatography (GC) is an analytical technique that allows the separation and identification of different compounds in a complex mixture of gases. The instrument for separating and identifying the compounds is called a gas chromatograph.
