應用：甲烷，總烴，非甲烷總烴的測定

非甲烷總烴(NMHC)通常是指除甲烷以外的所有可揮發(fā)的碳氫化合物(其中主要是C2-C8)的總稱。一般環(huán)境空氣中非甲烷總烴的含量不高,但隨著近年工業(yè)的發(fā)展,大量廢氣排入環(huán)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(huán)境和人類造成危害。

浩瀚色譜（山東）應用技術開發(fā)有限公司采用帶有雙柱單氫焰離子化檢測器的氣相色譜儀,直接進樣差量法測定非甲烷總烴的含量。方法檢出限為0.015mg/m3;RSD在0.9%~3.2%之間;加標回收率為95.4%~101.7%。該方法操作簡單,定量準確,結果符合實驗要求。

Application: determination of methane, total hydrocarbons, non-methane total hydrocarbons

Non-methane total hydrocarbons (NMHC) usually refers to all volatile hydrocarbons (mainly C2-C8) except methane. Generally, the content of non-methane total hydrocarbons in the 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. Exceeding a certain concentration of non-methane total hydrocarbons in the atmosphere, in addition to being directly harmful to human health, under certain conditions exposure to sunlight can also produce photochemical smog, which is harmful to the environment and humans.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a gas chromatograph with a dual-column single-hydrogen flame ionization detector to determine the content of non-methane total hydrocarbons by direct sample injection differential method. The detection limit of the method is 0.015 mg/m3; the RSD is between 0.9% and 3.2%; the recovery rate of standard addition is 95.4% to 101.7%. The method is simple to operate, quantitative and accurate, and the results meet the experimental requirements.
