- Scope
- This standard specifies a gas phase spectrometry-mass spectrometry method for the determination of six kinds of hydrochloric acid-related complexes expanded in ambient air. This standard is applicable to the determination of six volatile carboxylic acid compounds, including acetic acid, lactic acid, VE butyric acid, lactic acid, isovaleric acid and n-valeric acid, in ambient air and fugitive emission monitoring point air. When the sampling volume is 60L (standard state), the concentration volume is 1.0ml, the detection limit of the method is 0.2ug-70gAn, and the lower limit of determination is 0.8ug-28usgma. Jiantong sees Yin and enters.
