Determination of the specific surface area of solids by gas adsorption. BET method Ingestion-build-137917

Determination of the specific surface area of solids by gas adsorption. BET method Ingestion-build-1379171 Scope This International Standard specifies the determination of the overall (see Note) specific external and internal surface area of disperse (e. g. nano powders) or porous solids by measuring the amount of physically adsorbed gas according to the Brunauer, Emmett and Teller (BET) method (see Reference [1]). It takes account of the International Union for Pure and Applied Chemistry (IUPAC) recommendations of 1984 and 1994 (see References [7][8]).
