《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》（HJ 38-2017）和《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（HJ 604-2017 ）》

　　《HJ/T 38-1999》规定:用双柱双氢火焰离子化检测器气相色谱仪，注射器直接进样，分别测定样品中的总烃和甲烷含量，以两者之差得非甲烷总烃含量。同时以除烃空气求氧的空白值，以扣除总烃色谱峰中的氧峰干扰。

　　《HJ 604-2011》规定:将样品直接注入气相色谱仪，用氢火焰离子化检测器测定样品中总烃和氧二者的总量（以甲烷计），同时用除烃空气代替样品，可以测得氧的含量（以甲烷计），从二者的总量中扣除氧的含量后即为总烃的含量。

　　Determination of Total Hydrocarbons, Methane, and Non Methane in Fixed Source Waste Gas by Gas Chromatography (HJ 38-2017) and Determination of Total Hydrocarbons, Methane, and Non Methane in Environmental Air by Direct Injection Gas Chromatography (HJ 604-2017)

　　According to HJ/T 38-1999, a dual column dual hydrogen flame ionization detector gas chromatograph is used with a syringe for direct injection to determine the total hydrocarbon and methane content in the sample, and the difference between the two is used to obtain the non methane total hydrocarbon content. At the same time, the blank value of oxygen is calculated using hydrocarbon removal air to deduct the interference of oxygen peak in the total hydrocarbon chromatographic peak.

　　According to HJ 604-2011, the sample is directly injected into a gas chromatograph, and the total amount of total hydrocarbons and oxygen (calculated as methane) in the sample is determined using a hydrogen flame ionization detector. At the same time, the oxygen content (calculated as methane) can be measured by replacing the sample with hydrocarbon removal air. After deducting the oxygen content from the total amount of both, the total hydrocarbon content is obtained.

　　The new total hydrocarbon column developed by Haohan Chromatography is stable, reliable, with perfect peak shape and no branching. It has been widely used in the environmental, petrochemical, organic, inorganic and other chemical industries.
