本文将介绍表面孔径测定仪及使用方法,本文着重介绍使用方法。为了测定吸附量、计算比表面积和孔径分布,文章介绍了仪器常数的测定,在使用双气路法中等效死空间的扣除,样品的处理,取样量的多少及仪器启动等具体操作方法。另外关于比表面积测定原理和孔径分布测定原理及计算方法,BET公式的适用范围及其它测定方法等一些理论,也有所介绍。
This article will introduce surface pore size analyzer and the use of methods, this article focuses on the use of methods. In order to determine the adsorption capacity and calculate the specific surface area and pore size distribution, the article introduced the determination of instrument constant, the deduction of equivalent dead space in the double gas method, the sample processing, the amount of sample and the specific operation method of instrument start-up. In addition, the measurement principle of surface area and pore size distribution measurement principle and calculation method, the application range of BET formula and other measurement methods are also introduced.
