Standard Number: HJ 1220-2021(HJ1220-2021)
Chinese:环境空气 6种挥发性羧酸类化合物的测定 气相色谱-质谱法
English:Determination of 6 volatile carboxylic acid compounds in ambient air by gas chromatography-mass spectrometry
Effective Date:2022-06-01
Standard Applicability:This standard specifies the gas chromatography-mass spectrometry (GC-MS) method for the determination of six volatile carboxylic acid compounds in ambient air. This standard applies to the determination of six volatile carboxylic acid compounds such as acetic acid, propionic acid, n-butyric acid, acrylic acid, isovaleric acid and n-valeric acid in the ambient air and the air of the monitoring point of non-organized emissions. When the sampling volume is 60 L (under the standard condition), the concentration volume is 1.0 ml, the detection limit of the method is 0.2 μg/m3-7 μg/m3, and the lower limit of the method is 0.8 μg/m3-28 μg/m3. For details, please refer to Appendix A.
