4 An Introduction to Headspace Sampling in Gas Chromatography Partition Coefficients The previous description is simplified. In practice, the migration of compounds into the headspace phase does not just depend on their volatility but more on their affinity for the
The headspace sampler may present a flow shutdown or poor chromatography with decreased area counts or shifted retention times, caused by leaks or restrictions in the sampler. The hardware has a built-in restriction and pressure decay test that can be utilized to help with troubleshooting.

Headspace Gas Chromatography methods have been shown to be effective for the determination of ethanol in low concentrations in fermented beverages (6–8, 20–22). A significant advantage of such methods is the ability to minimize the interference of non-volatile constituents through utilizing the headspace injection ( 6 , 22 , 23 ).
