浩瀚非甲烷总烃的直接测定专用填充柱HH-NMHC-I

非甲烷总烃（NMHC）指从总烃中扣除甲烷以后其他气态有机化合物的总和[1]。一般环境空气中NMHC的含量不高，但近些年随着现代工业的飞速发展，大量废气排入环境空气中，使得NMHC成为很多国家环境大气的主要污染物。有数据表明，大气中NMHC浓度超过一定范围，会直接影响人体健康，导致光化学烟雾，危害*。

传统的非甲烷总烃的测定采用间接法，即先测定总烃和甲烷的含量，二者之差即为非甲烷总烃的含量，此法操作复杂，误差大。

浩瀚色谱（山东）应用技术开发有限公司，采用新技术，研发直接测定非甲烷总烃的含量的新方法， 效率高，定量准确可靠，结果满意。

Non-methane total hydrocarbons (NMHC) refers to the sum of other gaseous organic compounds after deducting methane from total hydrocarbons [1]. Generally, the content of NMHC in the ambient air is not high, but in recent years, with the rapid development of modern industry, a large amount of exhaust gas is discharged into the ambient air, making NMHC the main pollutant of the ambient air in many countries. Data show that the concentration of NMHC in the atmosphere exceeds a certain range, which will directly affect human health and cause photochemical smog, which is extremely harmful.

The traditional determination of non-methane total hydrocarbons uses an indirect method, that is, the content of total hydrocarbons and methane is determined first, and the difference between the two is the content of non-methane total hydrocarbons. This method is complicated to operate and has large errors.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. adopts new technology to develop a new method for directly determining the content of non-methane total hydrocarbons. It has high efficiency, accurate and reliable quantification, and satisfactory results.
