Gas chromatography (GC) is the technique for separating gases and volatile compounds in their gaseous state. In this technique, different chemical compounds are separated based on their volatility using inert gas, like helium, as a mobile phase. The mobile phase (gas) acts as the carrier of the different compounds present in the sample, which then interacts in the column …

The Basic Principles of Gas Chromatography. Gas chromatography relies on the principle of differential partitioning of compounds between a mobile gas phase and a stationary phase within a column. As a sample is vaporized and carried through the column by an inert gas, different components interact with the stationary phase to varying degrees.

The equilibrium for gas chromatography is partitioning, and the components of the sample will partition (i.e. distribute) between the two phases: the stationary phase and the mobile phase. Compounds that have a greater affinity for the stationary phase spend more time in the column and thus elute later and have a longer rete…
