摘要
甲烷是瓦斯的主要成分,是一种重要的温室气体.瓦斯的实时、在线监测对于煤矿企业的安全生产具有极其重要的意义.本文介绍了几种检测甲烷的方法———催化燃烧法、半导体气敏法、红外光谱法、气相色谱法、光纤法等的原理及应用,并对基于以上几种方法的瓦斯传感器的研究进展进行了综述.
The determination of methane online is of strong interest to the safety production in mine due to its potential to cause explosions and its known greenhouse effect. The review gives an account of the existing detection method for methane in air and environmental samples, such as calorimetric, semi-conduetiong metal oxides analysis, infrared spectral analysis, GC, and fiber optical analysis. The development of gas sensor based on each method was also reviewed.
