　　Haohan Chromatography, according to the "Determination of Total Hydrocarbons, Methane, and Non Methane Total Hydrocarbons in Environmental Air - Direct Injection Gas Chromatography Method" (HJ 604-2017), has achieved satisfactory results in the ability assessment. The results show that using direct injection gas chromatography with a dual valve dual column dual hydrogen flame ionization detector can simultaneously determine total hydrocarbons, methane, and non methane total hydrocarbons in environmental air, with high accuracy, precision, and repeatability of the determination results, short analysis time, and calibration curve correlation coefficients for total hydrocarbons and methane greater than 0.999. This method is suitable for daily detection of non methane total hydrocarbons in environmental air
