加強固定污染源中NMHC監(jiān)測有益于人體健康、環(huán)境安全與生態(tài)平衡，使用氣相色譜法配雙柱雙氫火焰離子檢測NMHC含量效果較好。
滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，根據(jù)HJ／T38-1999《固定污染源排氣中非甲烷總烴的測定氣相色譜法》標準改造氣象色譜儀，測試結(jié)果規(guī)定改造儀器合格，適用于固定污染源有組織排放和無組織排放的非甲烷總烴（NMHC）的檢測，可投入使用。NMHC的檢出量為4×10^-2ng，當(dāng)色譜進樣量為1．0mL時，方法的檢出濃度為0．2782mg／m^3，方法的定量測定濃度范圍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.
