Haohan Chromatography adopts the "Air and Waste Gas Monitoring and Analysis Methods (Fourth Edition)" P585~P587 Total Hydrocarbon and Non Methane Total Hydrocarbon Determination Method 1 (B), which uses a six way valve to quantitatively inject samples to determine the concentration of non methane total hydrocarbons in ambient air and waste gas. The instrument conditions are optimized, and the detection limit of the method is 0.13 mg/m3. The relative standard deviation of total hydrocarbons in the standard sample is 0.4%, the relative standard deviation of methane is 1.2%, the recovery rate of total hydrocarbons is 100.9%~101.6%, and the recovery rate of methane is 102.4%~102.6%. This method is easy to operate, fast in analysis, and satisfactory in experimental results.
