3 Principles of the method
Place the sample to be tested in a closed container, and heat it up to make the volatile components volatilize from the sample matrix.
When the phases reach equilibrium, the gas in the headspace is directly extracted for gas chromatographic analysis. Qualitative by retention time, quantification by peak area, using external standard
Quantitative
