Headspace-gas chromatography (HS-GC) analysis can be applied successfully for the analysis of VSCs in different liquid matrices. It can be also applied in physical chemistry studies of these compounds, being a valuable tool for acquiring data on gas–solid and gas–liquid systems.

An Introduction to Headspace Sampling in Gas Chromatography Phase Ratio Other factors that can affect the concentration of an analyte in the headspace phase are the respective volumes of the sample and the headspace in the sealed vial. The concentration of analyte in the sample and the headspace can be expressed respectively as Equations 2 and 3.
