本标准规定了测定环境空气和废气中氯化氢的离子色谱法。
本标准适用于环境空气和废气中氯化氢的测定。
对于环境空气，当采样体积为60 L（标准状态），定容体积为10.0 ml 时，方法检出限为0.02 mg/m3，测定下限为0.080 mg/m3。
对于固定污染源废气，当采样体积为10 L（标准状态），定容体积为50.0 ml 时，方法检出限为0.2 mg/m3，测定下限为0.80 mg/m3。

Scope

This standard specifies the ion chromatography method for the determination of hydrogen chloride in ambient air and waste gas. This standard is applicable to the determination of hydrogen chloride in ambient air and waste gas. For ambient air, when the sampling volume is 60 L (standard state) and the fixed volume is 10.0 ml, the method detection limit is 0.02 mg/m³ and the lower limit of determination is 0.080 mg/m³. For waste gas from fixed pollution sources, when the sampling volume is 10 L (standard state) and the fixed volume is 50.0 ml, the method detection limit is 0.2 mg/m³ and the lower limit of determination is 0.80 mg/m³.
