BET is one of the few methods available for surface area measurement and has the advantage of being able to give a measure of porosity. by the BET method. G. FAGERLUND (1). The theoretical background of the adsorption isotherm equation of Brunauer, Emmett and Teller is reviewed, together. Abstract. The theoretical background of the adsorption isotherm equation of Brunauer, Emmett and Teller is reviewed, together with the experimental techniques.

The BET method is widely used in surface science for the calculation of surface gong fm spin einloggen of solids by physical adsorption of gas molecules. It is not just BET surface area that can be measured using this method.
