本標準規(guī)定了測定環(huán)境空氣中總烴、甲烷和非甲烷總烴的直接進樣-氣相色譜法。

本標準適用于環(huán)境空氣中總烴、甲烷和非甲烷總烴的測定，也適用于污染源無組織排放監(jiān)控點空氣中總烴、甲烷和非甲烷總烴的測定。

當進樣體積為1.0 ml 時，本標準測定總烴、甲烷的檢出限均為0.06 mg/m3（以甲烷計），測定下限均為0.24 mg/m3（以甲烷計）；非甲烷總烴的檢出限為0.07 mg/m3（以碳計），測定下限為0.28 mg/m3（以碳計）。

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).
