At present, the determination of non-methane total hydrocarbons in ambient air often requires repeated injections to determine methane and total hydrocarbons separately. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. can simultaneously determine methane and total hydrocarbons at one time, and determine non-methane by calculating the difference. The concentration of total methane hydrocarbons, the experimental method is simple and easy to implement, the results are reliable, and the experimental efficiency is greatly improved.
