Porosity and Surface Area
The interaction of a solid with its surroundings is through the available surface area for adsorption of gas or vapour molecules. This also allows probing of materials’ surfaces including irregularities and pores. One of the most successful methods is based on the BET method for gas adsorption onto a solid surface. The adsorption method of Brunauer, Emmett and Teller (BET) is based on the physical adsorption of a vapour or gas onto the surface of a solid. Such data can be used to analyse the porosity of the materials being studied. Surface Measurement Systems have pioneered the use of both the Dynamic Vapor Sorption (DVS) and the Inverse Gas Chromatography (IGC) methods for determining the surface area and porosity of solid state materials.
