On September 10, 2013, the State Council issued the "Action Plan for Air Pollution Prevention and Control" and formulated specific ten policy implementation plans, commonly known as the "Ten Atmospheric Measures". This is a major strategic deployment made by the Chinese government based on a scientific assessment of the current atmospheric environment situation, pointing out the direction for the national air pollution prevention and control work, and becoming a programmatic document for China's air pollution prevention and control work. In order to fight the battle against air pollution, the national environmental monitoring department has also formulated a series of testing standards and issued them for implementation. Among them, HJ734-2014 "Determination of volatile organic compounds in exhaust gas from fixed pollution sources - Solid phase adsorption thermal desorption/gas chromatography-mass spectrometry" is used to determine 24 types of volatile organic compounds in exhaust gas from fixed pollution sources.

The fully automatic headspace sampler is a convenient and fast sample pre-treatment method in gas chromatography. Its principle is to place the sample to be tested in a closed container, heat it up to evaporate volatile components from the sample matrix, and achieve equilibrium in the gas-liquid (or gas-solid) phase. The top gas is directly extracted for chromatographic analysis, thereby verifying the composition and content of volatile components in the sample.

As an analytical method, the fully automatic headspace sampler is first and foremost simple, as it only takes the gas phase for analysis, greatly reducing the interference of the sample matrix on the analysis.
