非甲烷总烃(NMHC)通常是指除甲烷以外的所有可挥发的碳氢化合物(其中主要是C2-C8)的总称。一般环境空气中非甲烷总烃的含量不高,但随着近年工业的发展,大量废气排入环境空气中。大气中的非甲烷总烃超过一定浓度,除直接对人体健康有害外,在一定条件下经日光照射还能产生光化学烟雾,对环境和人类造成危害。

滕州市浩瀚色谱仪器技术服务有限公司，研发出一种改进型的非甲烷总烃测定气相色谱仪及其在环境监测中的应用。满足总烃和非甲烷总烃的检测要求,低检出浓度为0.2ng/ml。该分析方法采用单FID配置,消除双FID因FID的灵敏度的差异性引起误差。同时,改进的色谱仪还具有操作简单,工作效率高,准确性好的优点。

Non-methane total hydrocarbons (NMHC) generally refer to the general term for all volatile hydrocarbons other than methane, mainly C2-C8. Generally, the content of non-methane total hydrocarbons in ambient air is not high, but with the development of industry in recent years, a large amount of exhaust gas is discharged into the ambient air. The total non-methane hydrocarbons in the atmosphere exceed a certain concentration. In addition to being directly harmful to human health, under certain conditions, photochemical smog can also be generated by sunlight, causing harm to the environment and humans.

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. has developed an improved non-methane total hydrocarbon gas chromatograph and its application in environmental monitoring. Meet the detection requirements of total hydrocarbons and non-methane total hydrocarbons, the minimum detection concentration is 0.2 ng / ml. The analysis method uses a single FID configuration to eliminate errors caused by the difference in sensitivity of the FID due to the FID. At the same time, the improved chromatograph has the advantages of simple operation, high work efficiency and good accuracy.
