With the rapid development of domestic petrochemical industry, oil refining industry, waste incineration power generation and other industries, the problem of air pollution caused by non-methane hydrocarbons has attracted more and more attention, and its monitoring has become more frequent. The monitoring of non-methane total hydrocarbons in ambient air and stationary pollution source exhaust gas mostly uses gas chromatography.

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., there is a certain difference between the measured value and the true value obtained through method analysis, and the size of the measurement error will directly affect the reliability of the data. Uncertainty evaluation can effectively identify the factors that may cause the measurement results to deviate during the measurement process, thereby ensuring the accuracy of the measurement data. According to "CNAS-CL: 07 2011 Measurement Uncertainty Requirements", "JIF1059.1-2012 Measurement Uncertainty evaluation and expression", "HJ 38-2017 Determination of Total Hydrocarbons, Methane and Non-methane Total Hydrocarbons in Fixed Pollution Sources Gas Chromatography" and "HJ 604-2017 Determination of Total Hydrocarbons in Ambient Air, Direct Injection of Methane and Non-Methane Total Hydrocarbons-Gas Chromatography" and other related standards, using gas chromatography to quantitatively analyze the content of non-methane total hydrocarbons in gas samples Content, the uncertainty of the measurement result is evaluated, and the evaluation process is introduced systematically, and the composite uncertainty and the expanded uncertainty are given by calculation.
