Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses hydrogen flame ionization detector gas chromatography to determine non-methane total hydrocarbons in ambient air. The detection limits of the method were as follows: total hydrocarbons were 0.02 mg/m3, methane was 0.02 mg/m3, and non-methane total hydrocarbons were 0.02 mg/m3. Coefficient of variation: total hydrocarbons were 0.65%, methane was 0.55%, and non-methane total hydrocarbons were 3.06%. The recovery rate of standard addition: the total hydrocarbons are 101.2%~102.7%, and the methane is 100.7%~101.8%. The method is feasible and suitable for the determination of non-methane total hydrocarbons in ambient air.

​​​​​​​Name: methane column
Specifications: 1m*1/8
Model: HH-NMHC-I
