Porapak Q Methane Column Details:

Name: Methane column

Stationary phase: polymer beads

Specifications: 2m*1/8

Model: PQ

Application: Determination of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air


The determination of total non-methane hydrocarbons is an important part of environmental monitoring, which is usually completed by gas chromatography, and the difference between the content of total hydrocarbons and methane is the specific content of total non-methane hydrocarbons.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. determined total hydrocarbons, methane and non-methane total hydrocarbons in ambient air according to HJ 604-2017, using a 6890N chromatographic analyzer, selected appropriate chromatographic operating parameters, and calibrated with standard gas. The air sample was directly injected into the analyzer for analysis. The experimental results showed that the application of gas chromatography to determine the content of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air is simple, rapid, and has a good linear relationship with reliable accuracy and precision. .
