HJ 644-2013 Ambient air - Determination of volatile organic compounds-Sorbent adsorption and thermal desorption/gas chromatography mass spectrometry method (English Version)
This standard specifies the sorbent adsorption and thermal desorption / gas chromatography mass spectrometry method for determination of volatile organic compounds (VOCs) in ambient air.
This standard is applicable to the determination of 35 volatile organic compounds in the ambient air. This standard, if verified, may also be applicable to the determination of other nonpolar or weakly polar volatile organic compounds.
Where the sampling volume is 2L, the method detection limit of this standard is 0.3~1.0μg/m3 and the determination lower limit is 1.2~4.0μg/m3 as detailed in Appendix A.
