Aluminium oxide primarily used for the production of aluminium. Determination of specific surface area by nitrogen adsorption Ingestion-build-61878 Global awareness of the urgency1 Scope This International Standard specifies an instrumental method for the determination of specific surface area (SSA) of smelter grade alumina (SGA) by nitrogen adsorption by a single or multi point method. A multi point method is recommended due to the higher accuracy obtained; if a single point method is used, a lower result will be obtained. NOTE Annex A provides an explanation of the difference between single and multi point determined BET
