浩瀚境空气中总烃、甲烷和非甲烷总烃的测定甲烷柱GDX-502

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依据HJ 604-2017对环境空气中总烃、甲烷和非甲烷总烃进行测定,使用浩瀚GC-790型色谱分析仪,选择了合适的色谱操作参数,标准气体校正了分析仪,将空气样品直接进样分析。实验结果表明,应用气相色谱法测定环境空气中总烃、甲烷和非甲烷总烃含量,方法简便快速、线性关系良好,具有可靠的准确度和精密度。

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 ambient air is not high, but with the recent industrial With the development of the environment, a large amount of exhaust gas is discharged into the ambient air. The non-methane total hydrocarbons in the atmosphere exceed a certain concentration, which is not only directly harmful to human health, but under certain conditions, sunlight exposure can also produce photochemical smog, which is harmful to the environment and humans.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. measured total hydrocarbons, methane and non-methane total hydrocarbons in ambient air in accordance with HJ 604-2017. Using Haohan GC-790 chromatographic analyzer, appropriate chromatographic operating parameters and standards were selected. The gas calibrated the analyzer, and the air sample was directly injected for analysis. Experimental results show that the application of gas chromatography to determine the content of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air is simple and rapid, with a good linear relationship, and reliable accuracy and precision.
