在石油化工生产中产生的大量C_1～C_9烷烃和烯烃的混合物,统称为总烃。烃类易燃易爆,且污染环境和危害人体健康。目前车间空气监测中尚未有测定总烃的方法。


甲烷是大气中对温室效应影响仅次于二氧化碳的气体,甲烷的含量对于辐射过程和气候发展趋势的研究是特别重要;通过监测地面环境空气中甲烷的含量来分析其来源,能够为大气化学的研究提供非常重要的依据.浩瀚色谱（山东）应用技术开发有限公司针对环境空气中甲烷的测定,介绍了常用的两种测量方法.对每种方法的测量原理,特点及适用范围等方面进行了详细的阐述,对GC与TDLAS两种方法进行了详细的比较.

The mixture of a large number of C_1-C_9 alkanes and olefins produced in petrochemical production is collectively referred to as total hydrocarbons. Hydrocarbons are flammable and explosive, pollute the environment and endanger human health. At present, there is no method for measuring total hydrocarbons in workshop air monitoring.


Methane is the gas in the atmosphere second only to carbon dioxide in its impact on the greenhouse effect. The content of methane is particularly important for the study of radiation processes and climate development trends. By monitoring the content of methane in the ground ambient air to analyze its source, it can be used for atmospheric chemistry. The research provides a very important basis. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. introduces two commonly used measurement methods for the determination of methane in ambient air. The measurement principle, characteristics and application scope of each method are discussed. A detailed elaboration and a detailed comparison of the GC and TDLAS methods are given.
