Haohan Chromatography uses sampling bags for sampling, and dual stainless steel packed columns and single FID detectors for direct injection gas chromatography to determine non methane total hydrocarbons in fixed pollution source exhaust gas. The results showed that under experimental conditions, the correlation coefficients of the calibration curves for low or high concentrations of methane and total hydrocarbons were all above 0.9996. When the injection volume was 1.0 mL, the detection limit of methane (measured by methane) was 0.053 mg/m3, and the detection limit of total hydrocarbons (measured by methane) was 0.056 mg/m3. The relative standard deviation of methane is between 1.32% and 1.91%, and the relative error is between -3.77% and 7.00%; The relative standard deviation of total hydrocarbons is between 0.92% and 4.05%, and the relative error is between -8.11% and 6.69%. This method is easy to operate, has high accuracy, and can meet the determination of non methane total hydrocarbons in fixed pollution source exhaust gas.
