应用：甲烷，总烃，非甲烷总烃的测定

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。

浩瀚色谱（山东）应用技术开发有限公司采用带有双柱单氢焰离子化检测器的气相色谱仪,直接进样差量法测定非甲烷总烃的含量。方法检出限为0.015mg/m3;RSD在0.9%~3.2%之间;加标回收率为95.4%~101.7%。该方法操作简单,定量准确,结果符合实验要求。

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.
