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）。

This standard specifies direct injection-gas chromatography 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 to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in the air at the unorganized emission monitoring point of pollution sources.
When the injection volume is 1.0 ml, the detection limit of total hydrocarbon and methane measured by this standard is 0.06 mg/m3 (in terms of methane), and the lower limit of determination is 0.24 mg/m3 (calculated as methane); non-methane total hydrocarbon The detection limit was 0.07 mg/m3 (calculated as carbon) and the lower limit of determination was 0.28 mg/m3 (calculated as carbon).
