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.
