See Chinese contents: HJ 644-2013 HJ 644-2013: Ambient air. Determination of volatile organic compounds. Sorbent adsorption and thermal desorption/gas chromatography mass spectrometry method
This Standard specifies the sorbent adsorption and thermal desorption / gas chromatography mass spectrometry method for the determination of volatile organic compounds (VOCs) in ambient air. This Standard applies to the determination of 35 volatile organic compounds in ambient air. If verified, this Standard can also be applied to the determination of other non-polar or weakly polar volatile organic compounds.
