固体的比表面积,即每一克固体所具有的总的表面积,在涉及表面化学和表面物理的各种过程中,都是一个重要的指标。连续流动色谱法测定比表面,仪器简单,没有汞害。速度比经典的静态方法快得多。我国已有了定型仪器——ST-03型表面孔径测定仪.比表面的测定,受各种因素的影响。各种测试方法之间又有差异.因而比表面数据本身往往是相对某一方法某种条件而言的。所以,测定数据的重复性是
The specific surface area of a solid, ie, the total surface area per gram of solid, is an important indicator in various processes involving surface chemistry and surface physics. Continuous flow chromatography to determine the specific surface, the instrument is simple, no mercury damage. Speed is much faster than classic static methods. China has a stereotypes instrument - ST-03 surface pore size analyzer. Determination of specific surface, affected by various factors. There are differences between the various test methods, so the specific surface data itself is often relative to a method for some conditions. Therefore, the repeatability of the measurement data is
