在石油化工生产中产生的大量C_1～C_9烷烃和烯烃的混合物,统称为总烃。烃类易燃易爆,且污染环境和危害人体健康。目前车间空气监测中尚未有测定总烃的方法。
滕州市浩瀚色谱仪器技术服务有限公司，采用六通阀进样，双毛细管柱、双FID检测器气相色谱法，一次进样即可测得大气中的CH4、总烃及非甲烷总烃（NMHC）的测试数据．同时对色谱中FID检测器中出现的氧峰初步可认定为“干扰峰”，在分析中可忽略不计．方法的检出限：CH4 0．03mg／m3，总烃0．04mg／m3，NMHC0．06mg／m3．变异系数：CH4 3．81％，总烃2．07％，NHMC5．07％．加标回收率：CH4 96．1％，NHMC96．1％～98％．

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses six-port valve injection, double capillary column and double FID detector gas chromatography to measure CH4, total hydrocarbons and non-methane total hydrocarbons in the atmosphere (NMHC). Test data. At the same time, the oxygen peak appearing in the FID detector in the chromatogram can be initially identified as “interference peak”, which can be ignored in the analysis. The detection limit of the method: CH4 0.03mg/m3, total hydrocarbon 0.04mg/m3, NMHC0.06mg/m3. Coefficient of variation: CH4 3.81%, total hydrocarbon 2.07%, NHMC 5.07%. The recoveries were spiked: CH4 96.1%, NHMC 96.1%-98%.
