PE珀金埃尔默GDX104甲烷柱2m*1/8

名称：甲烷柱

固定相：高分子小球180um--250um
规格：2m*1/8
型号：GDX-104

我国环境标准《hj604-2017环境空气总烃、甲烷和非甲烷总烃的测定直接进样-气相色谱法》和《hj38-2017固定污染源废气总烃、甲烷和非甲烷总烃的测定气相色谱法》中规定的实验室检测方法，也是国内在线和便携设备比较普遍采用的方法。该方法主要采用将气体样品直接注入具氢火焰离子化检测器的气相色谱仪，分别在总烃柱和甲烷柱上测定总烃和甲烷的含量，两者之差即为非甲烷总烃的含量。同时以除烃空气代替样品，测定氧在总烃柱上的响应值，以扣除样品中的氧对总烃测定的干扰。

 

Name: Methane column

Stationary phase: polymer beads 180um--250um
Specifications: 2m*1/8
Model: GDX-104

my country's environmental standards "hj604-2017 Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons in Ambient Air Direct Injection-Gas Chromatography" and "Hj38-2017 Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons in Stationary Pollution Source Gas Chromatography" The laboratory testing method stipulated in the ” is also the method commonly used in domestic online and portable equipment. The method mainly uses the gas sample directly injected into a gas chromatograph with a hydrogen flame ionization detector, and the contents of total hydrocarbons and methane are measured on the total hydrocarbon column and the methane column respectively, and the difference between the two is the content of non-methane total hydrocarbons. . At the same time, the sample was replaced by hydrocarbon-removing air, and the response value of oxygen on the total hydrocarbon column was measured to deduct the interference of oxygen in the sample on the determination of total hydrocarbons.
