浩瀚MS-5A甲烷柱1m*1/8

标准规定了测定固定污染源废气中总烃、甲烷和非甲烷总烃的气相色谱法。标准适用于固定污染源有组织排放废中的总烃、甲烷和非甲烷总烃的测定。

方法原理

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，分别在总烃柱和甲院柱上则定总烃和甲烧的含里，两者之差即为非甲烷总的含量。同时以腺经空气代替样品，则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。

The standard specifies the gas chromatography method for determining total hydrocarbons, methane, and non methane total hydrocarbons in exhaust gas from fixed pollution sources. The standard is applicable to the determination of total hydrocarbons, methane, and non methane total hydrocarbons in organized emissions of waste from fixed pollution sources.



Method principle



Inject the gas sample directly into a gas chromatograph equipped with a hydrogen flame ionization detector, and determine the content of total hydrocarbon and methanol on the total hydrocarbon column and the methanol column, respectively. The difference between the two is the total content of non methane. At the same time, replacing the sample with glandular air, the response value of oxygen on the total hydrocarbon column is determined to deduct the interference of oxygen in the sample on the determination of total hydrocarbons.
