《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。
针对固定污染源、工厂烟囱气、喷漆房等复杂排放气体，浩瀚色谱（山东）应用技术开发有限公司，研制的HH-BLQ硅烷化玻璃微珠总烃合峰专用总柱有效解决总烃峰分离、分叉峰的难题，烷烃、烯烃、芳香烃和含氧化合物等组分在总烃柱上只出一个合峰。此柱适合应用于在线色谱和固定污染源的总烃检测。

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.
