Standard Number: HJ 1271-2022(HJ1271-2022)
Chinese:环境空气 颗粒物中甲酸、乙酸和乙二酸的测定 离子色谱法
English:Determination of formic, acetic and glycolic acids in ambient air particulate matter Ion Chromatography
Effective Date:2023-06-15
Standard Applicability:This standard specifies the determination of formic acid, acetic acid and ethanedioic acid in ambient air particulate matter ion chromatography. This standard applies to the determination of formic acid, acetic acid and ethanedioic acid in ambient air and non-organized emission monitoring point air particulate matter. The minimum detectable amount of formic acid, acetic acid and ethanedioic acid in this standard is 0.8 μg ~ 1.9 μg. When the sampling volume of ambient air is 144 m3 (actual state), the volume of extraction solution is 100 ml, and the volume of injection is 200 μl, the detection limit of this method is 0.006 μg/m3 ~ 0.02 μg/m3, and the lower limit of the determination is 0.024 μg/m3 ~ 0.08 μg/m3. When the sampling volume of air at the monitoring point of unorganized emission is 6 m3 (standard state), the volume of extraction solution is 100 ml, and the sampling volume is 200 μl, the detection limit of this method is 0.2 μg/m3-0.4 μg/m3, and the lower limit of the measurement is 0.8 μg/m3-1.6 μg/m3, please refer to Appendix A for details.
