Determination of non-methane total hydrocarbons in waste gas from stationary pollution sources by portable hydrogen flame ionization detector

Name: Pre-column
Stationary phase: polymer beads
Granularity: 60-80 mesh
Specifications: 0.8m*1/8
Model: Porapak Q
Application: Determination of non-methane total hydrocarbons in waste gas from stationary pollution sources by portable hydrogen flame ionization detector

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has determined the detection limits of non-methane total hydrocarbons by the portable hydrogen flame ionization detector method (catalytic oxidation method and gas chromatography) through laboratory and stationary pollution source waste gas field comparison tests. The performance indicators such as conversion efficiency, precision and accuracy were studied. The laboratory test results showed that the detection limit of the portable hydrogen flame ionization detector method for the determination of non-methane total hydrocarbons (0. 3 mg/m~3), the conversion efficiency (98. 2%), precision (3. 49%), and accuracy (-2. 38%) basically meet the requirements of the method technical indicators, but for the catalytic oxidation method, it is necessary to focus on its conversion efficiency. Fixed pollution source waste gas site The comparative test results show that the relative accuracy (33. 2%) and relative error (-9. 27%~23. 7%) of the portable hydrogen flame ionization detector method and the laboratory method can basically meet the test method. The test requirements and trends are also consistent, which is suitable for field tests.
