5E-CH2000元素分析仪测定煤中碳、氢元素的技术探讨

Discussion on the Technology of the Determination of Carbon and Hydrogen in Coal by the 5E-CH2000 Element Analyzer

碳和氢是煤中有机质的主要组成元素,它们在煤中所占的比例相当大,且与煤的特性有着密切的关系。故检测的准确与否,是正确表征该煤种特征的关键所在。结合实际论述了用红外吸收法测定煤中碳、氢元素的基本原理,总结了正确应用红外吸收法测碳、氢的几个关键点及注意事项。

Carbon and hydrogen are major components of the organics which take up a considerable proportion in coal, and have a close relationship with coal characteristics. Therefore, whether the detection is accurate or not is the key to the correct characterization of the characteristics of coal. This thesis discusses the basic principle according to the reality and summarizes several key techniques when infrared absorption method is used in measuring elements such as carbon and hydrogen.
