摘要
本文通过开展样品测试,对《固定污染源废气低浓度颗粒物的测定重量法》(HJ 836—2017)的检出限和精密度进行验证,同时将其和《固定污染源排气中颗粒物的测定与气态污染物采样方法》(GB/T 16157—1996)进行对比。结果发现,《固定污染源废气低浓度颗粒物的测定重量法》(HJ 836—2017)在测定低浓度颗粒物时更有优势。
This paper carried out sample tests to verify the detection limit and precision of the"Gravimetric Method for the Determination of Low Concentration Particulate Matters in Exhaust Gases from Stationary Pollution Sources"(HJ 836—2017),and compare it with the"Determination of Particulate Matter in Exhaust from Stationary Pollution Sources and Sampling Methods of Gaseous Pollutants"(GB/T 16157—1996).It was found that the"Gravimetric Method for the Determination of Low Concentration Particulate Matter in Exhaust Gases from Stationary Pollution Sources"(HJ 836—2017)is more advantageous in the determination of low-concentration particulate matter.
