- Scope
- The standard solution used in the test is a volatile toxic compound. The solution preparation process should be performed in a fume hood, and the operator should wear protective equipment. Scope: This standard specifies the adsorption tube sampling-thermal desorption/gas chromatography-mass spectrometry method for the determination of volatile organic compounds (VOCs) in ambient air. This standard is applicable 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 2L, the detection limit of this standard method is 0.3~1.0μg/m³, and the lower limit of determination is 1.2~4.0μg/m³.
