Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., based on non-methane total hydrocarbon emission standards, analysis methods and actual monitoring conditions, defines non-methane total hydrocarbons, abnormal peak patterns of total hydrocarbons, oxygen peak interference, method detection limit determination and sampling container The problems in selection and other aspects were discussed. The results show that the derivatives of gaseous hydrocarbons belong to non-methane total hydrocarbons. Hydrocarbon derivatives and column types are the main reasons for the abnormal peak pattern of total hydrocarbons. Using hydrocarbon-removing air as a carrier gas can eliminate the interference of oxygen peaks. For the difference result, the detection limit should be determined according to the EPA SW-846 standard. The PVF air bag has a low background, good air tightness and chemical inertness, and is the best non-methane total hydrocarbon sampling container.
