To measure non-methane total hydrocarbons in ambient air, it is often necessary to repeat the sample injection twice to measure methane and total hydrocarbons respectively. It can simultaneously measure methane and total hydrocarbons at one time, and the concentration of non-methane total hydrocarbons can be determined by calculating the difference. The experimental method is simple and easy to implement. , the results are reliable, and the experimental efficiency is greatly improved.
