加强固定污染源中NMHC监测有益于人体健康、环境安全与生态平衡，使用气相色谱法配双柱双氢火焰离子检测NMHC含量效果较好。
滕州市浩瀚色谱仪器技术服务有限公司，根据HJ／T38-1999《固定污染源排气中非甲烷总烃的测定气相色谱法》标准改造气象色谱仪，测试结果规定改造仪器合格，适用于固定污染源有组织排放和无组织排放的非甲烷总烃（NMHC）的检测，可投入使用。NMHC的检出量为4×10^-2ng，当色谱进样量为1．0mL时，方法的检出浓度为0．2782mg／m^3，方法的定量测定浓度范围0．12～32mg／m^3。

Strengthening NMHC monitoring in fixed pollution sources is beneficial to human health, environmental safety and ecological balance. It is better to use gas chromatography with double column double hydrogen flame ion to detect NMHC content.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd., according to HJ/T38-1999 "Gas Chromatography for Determination of Non-methane Total Hydrocarbons in Fixed Pollution Source Exhaust Gases", the gas chromatograph is modified. The test results stipulate that the modified instruments are qualified and suitable for fixed pollution sources. The detection of organized and unorganized emissions of non-methane total hydrocarbons (NMHC) can be put into use. The detection amount of NMHC was 4×10^-2ng. When the chromatographic injection volume was 1.0mL, the detection concentration of the method was 0.2782mg/m^3, and the quantitative concentration range of the method was 0.12～32mg/ m^3.
