《固定污染源廢氣 總烴、甲烷和非甲烷總烴的測定 氣相色譜法》（HJ 38-2017）和《環(huán)境空氣 總烴、甲烷和非甲烷總烴的測定 直接進樣-氣相色譜法（HJ 604-2017 ）》

　　《HJ/T 38-1999》規(guī)定:用雙柱雙氫火焰離子化檢測器氣相色譜儀，注射器直接進樣，分別測定樣品中的總烴和甲烷含量，以兩者之差得非甲烷總烴含量。同時以除烴空氣求氧的空白值，以扣除總烴色譜峰中的氧峰干擾。

　　《HJ 604-2011》規(guī)定:將樣品直接注入氣相色譜儀，用氫火焰離子化檢測器測定樣品中總烴和氧二者的總量（以甲烷計），同時用除烴空氣代替樣品，可以測得氧的含量（以甲烷計），從二者的總量中扣除氧的含量后即為總烴的含量。

　　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.
