浩瀚HH-NMHC-1环境空气中非甲烷总烃的直接测定专用填充柱

非甲烷总烃(non methane total hydrocarbon,缩写NMHC)是存在于环境空气中除甲烷之外的所有碳氢化合物的总称.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.。

目前测定环境空气中非甲烷总烃,往往要反复两次进样分别测定甲烷与总烃,通过计算差值测定非甲烷总烃的浓度,
此法有时出现负值，困扰着广大的分析工作者。

浩瀚色谱（山东）应用技术开发有限公司，研发一根色谱柱，直接进样测定非甲烷总烃的含量，实验方法简单易行,结果可靠,大大提高了实验效率.。此柱为浩瀚色谱，独树一帜的产品。

Non-methane total hydrocarbons (abbreviated as NMHC) are the general term for all hydrocarbons existing in the ambient air except methane. When the non-methane total hydrocarbons in the atmosphere exceed a certain concentration, in addition to being directly harmful to human health, Under certain conditions, sunlight exposure can also produce photochemical smog, which is harmful to the environment and humans.

At present, to measure non-methane total hydrocarbons in ambient air, it is often necessary to repeatedly inject samples twice to measure methane and total hydrocarbons, respectively, and to determine the concentration of non-methane total hydrocarbons by calculating the difference.
This method sometimes has negative values, which troubles the majority of analysts.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a chromatographic column to directly measure the content of non-methane total hydrocarbons. The experimental method is simple and easy to implement, the results are reliable, and the experimental efficiency is greatly improved. This column is a unique product of the vast chromatography.
