Scope

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.
When the sampling volume is 2 L, the detection limit of the method of this
Standard is 0.3~1.0 μg/m3; the lower limit of determination is 1.2~4.0 μg/m3.
See Appendix A for details.
