Flexible methane capillary column
Highly flexible methane capillary column Details:


The second type methane capillary column overcomes the shortcomings of the first type column, which is brittle and easy to break. It has high toughness, good elasticity, and is not easy to break. It is a unique product of the vast chromatogram.


Methane capillary column:

Specification: 30m*0.32mm*25um

Model: HH-PLOT-Molecular sieve-II
Application: Suitable for "HJ 38-2017 Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons in Fixed Pollution Sources Gas Chromatography", "HJ 604-2017 Determination of Ambient Air Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons Direct Sample Injection- Gas Chromatography


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has passed the laboratory and on-site comparison tests of fixed pollution source waste gas to determine the detection limit of non-methane total hydrocarbons by the portable hydrogen flame ionization detector method (catalytic oxidation method and gas chromatography). Research on performance indicators such as transformation efficiency, precision and accuracy. Laboratory test results show that the detection limit (0.3 mg/m~3), conversion efficiency (98.2%), precision (3.49%) of non-methane total hydrocarbons determined by the portable hydrogen flame ionization detector method ), accuracy (-2.38%) basically meets the requirements of the technical indicators of the method, but for the catalytic oxidation method, it is necessary to focus on its conversion efficiency. The on-site comparison test results of the fixed pollution source exhaust gas show that the relative accuracy (33.2%) and relative error (-9. 27% ~ 23. 7%) of the test results of the portable hydrogen flame ionization detector method and the laboratory method are basically It can meet the test requirements of the test method, the trend is also consistent, and it is suitable for on-site testing.
