1.Main Purpose

By heating and increasing the temperature, volatile components are volatilized from the sample matrix, reaching equilibrium in the gas-liquid (or gas-solid) two-phase system. The top gas is directly extracted for chromatographic analysis to determine the composition and content of volatile components in the sample. It is commonly used for the pretreatment of volatile organic compounds in water, soil, or solid/liquid samples.
