 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 Determination of Total Hydrocarbons, Methane, and Non Methane in Environmental Air - Direct Injection Gas Chromatography (Release)

This standard replaces HJ 604-2011 on March 1, 2018 for the determination of total hydrocarbons in ambient air by gas chromatography

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 is applicable to the determination of total hydrocarbons, methane, and non methane total hydrocarbons in the ambient air, as well as the determination of total hydrocarbons, methane, and non methane total hydrocarbons in the air of unorganized emission monitoring points of pollution sources.

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