应用：直接法测定非甲烷总烃

     鉴于大气中非甲烷总烃类的有机物的种种危害，对污染源、交通要道、工业园以及 厂界等敏感区域进行非甲烷总烃的实时监控和管制非常有必要。国外从上世纪就开始监测 空气中的非甲烷总烃的含量，先后发展了冷凝-重量法、燃烧法、红外分光法等，但这些技 术均有其使用限制，操作复杂等缺点，终未获得广泛应用。

     浩瀚色谱（山东）应用技术开发有限公司，采用直接法测定非甲烷总烃，无需测定总烃及甲烷，再通过差量法得出非甲烷总烃的含量，更加准确，效率高。

Direct method for determination of total non-methane hydrocarbons
Direct method for determination of total non-methane hydrocarbons Details:

Name: Packed column
Stationary phase: dedicated
Model: HH-NMHC
Application: Direct determination of non-methane total hydrocarbons

      In view of the various hazards of non-methane total hydrocarbons in the atmosphere, it is very necessary to monitor and control non-methane total hydrocarbons in sensitive areas such as pollution sources, traffic arteries, industrial parks, and factory boundaries. Foreign countries have been monitoring the content of non-methane total hydrocarbons in the air since the last century, and have successively developed condensation-gravity method, combustion method, infrared spectroscopy, etc., but these technologies have their shortcomings such as limited use and complicated operation, and they have not been obtained in the end. widely used.

      Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. uses a direct method to determine total non-methane hydrocarbons, without the need to determine total hydrocarbons and methane, and then obtains the content of non-methane total hydrocarbons through a differential method, which is more accurate and efficient.
