HJ 1219-2021 (English Version) PDF

Scope: This standard specifies a gas phase multi-method for the determination of pyridine in ambient gases and exhaust gases. This standard is applicable to the determination of pyridine in ambient air, air at unorganized emission monitoring points and organized emissions from stationary pollution sources. When collecting ambient air and unorganized emission monitoring point air, the sampling volume is L, and the fixed volume of the absorption liquid is 10 ml, the detection limit of the method is 0.02 mgmm, and the lower limit of determination is -0.08 mgm3s. When collecting organized emissions from fixed pollution sources For waste gas, the sampling volume is 30L, and when the fixed volume of the absorption liquid is S0 ml, the output limit of the method is 009mam, and the lower limit is 0.36 mg/m.
