 HJ 604-2017 环境空气 总烃、甲烷和非甲烷总烃的测定 直接进样-气相色谱法（发布稿）

本标准于2018-3-1代替HJ 604-2011 环境空气 总烃的测定 气相色谱法 

本标准规定了测定环境空气中总烃、甲烷和非甲烷总烃的直接进样-气相色谱法。

本标准适用于环境空气中总烃、甲烷和非甲烷总烃的测定，也适用于污染源无组织排放监控点空气中总烃、甲烷和非甲烷总烃的测定。

当进样体积为1.0 ml 时，本标准测定总烃、甲烷的检出限均为0.06 mg/m3（以甲烷计），测定下限均为0.24 mg/m3（以甲烷计）；非甲烷总烃的检出限为0.07 mg/m3（以碳计），测定下限为0.28 mg/m3（以碳计）。

HJ 604-2017 Ambient Air Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons Direct Injection-Gas Chromatography (Release)

 HJ 604-2017 Ambient Air Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons Direct Injection-Gas Chromatography (Release)

This standard replaces HJ 604-2011 Ambient air-Determination of total hydrocarbons-Gas chromatography on 2018-3-1

This standard specifies the direct injection-gas chromatography method for the determination of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air.

This standard applies to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air, and also applies to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in the air at monitoring points of fugitive emissions from pollution sources.

When the injection volume is 1.0 ml, the detection limit of this standard for the determination of total hydrocarbons and methane is 0.06 mg/m3 (calculated as methane), and the lower detection limit is 0.24 mg/m3 (calculated as methane); non-methane total hydrocarbons The detection limit is 0.07 mg/m3 (calculated by carbon), and the lower limit of determination is 0.28 mg/m3 (calculated by carbon).
