Scope

Main technical content: Under certain temperature conditions, the volatile components of tea samples in the headspace bottle evaporate into the upper space, generating vapor pressure. When the gas-solid two phases reach thermodynamic dynamic equilibrium, their material composition and concentration remain basically consistent in the two phases. Then, the solid-phase microextraction fiber head is used to adsorb and extract the substances in the gas phase. After being analyzed through the injection port, the substances are separated by chromatography. Subsequently, the substances are qualitatively analyzed by mass spectrometer, and the relative content of flavor volatile substances is determined by the internal standard relative content method
