非甲烷總烴(NMHC)通常是指除甲烷以外的所有可揮發的碳氫化合物(其中主要是C2-C8)的總稱。一般環境空氣中非甲烷總烴的含量不高,但隨著近年工業的發展,大量廢氣排入環境空氣中。大氣中的非甲烷總烴超過一定濃度,除直接對人體健康有害外,在一定條件下經日光照射還能產生光化學煙霧,對環境和人類造成危害。

滕州市浩瀚色譜儀器技術服務有限公司，研發出一種改進型的非甲烷總烴測定氣相色譜儀及其在環境監測中的應用。滿足總烴和非甲烷總烴的檢測要求,低檢出濃度為0.2ng/ml。該分析方法采用單FID配置,消除雙FID因FID的靈敏度的差異性引起誤差。同時,改進的色譜儀還具有操作簡單,工作效率高,準確性好的優點。

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.
