Basic principles of headspace analysis. A headspace sample is usually prepared in a vial containing the sample, the dilution solvent, a matrix modifier and the headspace. Volatile components from complex sample mixtures can be extracted from non-volatile sample components and isolated in the headspace or gas portion of a sample vial.

Sample preparation: Each sample vial was identically prepared: 1 g of dried tea placed into a 20 mL vial. Addition of 10 mL HPLC grade water and 10 μL of a halophenol mix (nine compounds) in diethyl ether solvent.
Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [12] and is still actively used. With this technique, only the gas phase above the sample is introduced into the GC column.
