Headspace gas chromatography (Headspace GC) is used to measure volatile compounds that are in the vapor above a solid or liquid sample in a sealed vial.

'Headspace' is the gas space above the sample in a chromatography vial. Volatile sample components diffuse into the gas phase, forming the headspace gas.
