HJ 1154-2020 (English Version) PDF

Scope: This standard specifies a high-performance liquid chromatography method for the determination of aldehydes and ketones in ambient air and air at fugitive emission monitoring points. This standard applies to formaldehyde, acetaldehyde, acrolein, acetone, propionaldehyde, crotonaldehyde, 2-butanone, n-butyraldehyde, benzaldehyde, isovaleraldehyde, n-valeraldehyde in the air at ambient air and unorganized emission monitoring points , n-hexanal, o-toluene, m-methylbenzaldehyde, p-methylbenzaldehyde and 2,5-dimethylbenzaldehyde, a total of 16 aldehyde and ketone compounds were determined. When the sample volume is 2.0 ml and the injection volume is 10 μl, the minimum detection amount of aldehydes and ketones is 0.024 μg ~ 0.060 μg. When the sampling volume is 20 L (under standard conditions), the detection rate of the method is The limit is 0.002 mg/m3～0.003 mg/m3, and the lower limit of determination is 0.008 mg/m3～0.012 mg/m3. See Appendix A for details.
