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.
For complex emission gases such as fixed pollution sources, factory chimney gas, and paint spraying rooms, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed the HH-BLQ Silanized Glass Bead Total Hydrocarbon Combined Peak Dedicated Total Column, which effectively solves the problem of total hydrocarbon peak separation and branching peaks. Components such as alkanes, alkenes, aromatic hydrocarbons, and oxygen-containing compounds only have one combined peak on the total hydrocarbon column. This column is suitable for online chromatography and total hydrocarbon detection from stationary sources.
