Abstract

The determination methods of the surface area and pore size distribution (PSD) of a solid have been extensively described. The surface area and PSD are important as the basic properties for a powder and porous material. Nowadays the surface area and PSD are easily obtained by an automatic measuring instrument. However, there is no method which covers the complete range of a specific surface area and a pore size. All of the methods have their limits of measurement. In many cases the definitions of the surface area and pore size in each method differ from one another. The features and principles of the methods have been discussed mainly in order to select an appropriate method and to analyze data exactly.
