Inverse Gas Chromatography and Dynamic Vapor Sorption are two methods of solid surface characterization isotherms. The exploitation of the adsorption and desorption isotherms leads to the calculation of specific surface area and surface energy of the divided solids under test. The powders used are gamma and alpha alumina. The aim of this study is to compare the results obtained by these both techniques.
