Gas Chromatography, or GC, is a technique that is used to separate, detect, and quantify small volatile compounds in the gas phase.
In GC, liquid samples are vaporized, then carried by an inert gas through a long, thin column. Analytes are separated based on their chemical affinity with a coating on the inside of the column.
