　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. conducted research on performance indicators such as detection limit, conversion efficiency, precision, and accuracy of portable hydrogen flame ionization detector method (catalytic oxidation method and gas chromatography method) for determining non methane total hydrocarbons through laboratory and fixed pollution source exhaust gas on-site comparison testing. The laboratory test results showed that the detection limit of portable hydrogen flame ionization detector method for determining non methane total hydrocarbons was 0 3 mg/m3), conversion efficiency (98 2%), precision (3.49%), accuracy (-2 38%) basically meets the requirements of the method's technical indicators, but for the catalytic oxidation method, it is still necessary to focus on its conversion efficiency. The on-site comparison test results of fixed pollution source exhaust gas show that the relative accuracy of the portable hydrogen flame ionization detector method and the laboratory method test results is (33 2%), relative error (-9.27%~23 7%) can basically meet the testing requirements of the testing method and maintain consistent trend, suitable for on-site testing
