BET theory aims to explain the physical adsorption of gas molecules on a solid surface and serves The BET method is widely used in surface. The surface area determined by BET is thus normally larger than the surface area determined by air permeability. The method used complies with Ph. Eu. Brunauer–Emmett–Teller (BET) theory aims to explain the physical adsorption of gas . The BET method is widely used in surface science for the calculation of  ‎ Concept · ‎ Derivation · ‎ Applications · ‎ Activated Carbon. Ein Gas , häufig Stickstoff , wird über das zu untersuchende Material geleitet. P0 is the saturation pressure of adsorbate at the temperature of adsorption. Measuring surface area with BET.
