Determination of 6 Volatile Carboxylic Acid Compounds in Ambient Air
Determination of 6 Volatile Carboxylic Acid Compounds in Ambient Air Details:

Name: capillary column
Fixative: nitroterephthalic acid-modified polyethylene glycol
Specifications: 30m*0.25mm*0.25um
Model: HH-FFAP
Application: HJ 1220-2021 Determination of 6 Volatile Carboxylic Acid Compounds in Ambient Air Gas Chromatography-Mass Spectrometry

This standard specifies a gas chromatography-mass spectrometry method for the determination of 6 volatile carboxylic acid compounds in ambient air.
This standard is applicable to the determination of 6 volatile carboxylic acid compounds, including acetic acid, propionic acid, n-butyric acid, acrylic acid, isovaleric acid and n-valeric acid, in ambient air and in the air of fugitive emission monitoring points.
When the sampling volume is 60 L (in the standard state) and the concentration volume is 1.0 ml, the detection limit of the method is 0.2 μg/m3～7 μg/m3, and the lower determination limit is 0.8 μg/m3～28 μg/m3. See Appendix A for details.
