Brunauer-Emmett-Teller (BET) Surface Area Determination - Test Method - BS 4359-1:1996 (ISO 9277:1)

BS 4359-1:1996 (ISO 9277:1995) test method determining the specific surface area of a variety of materials by the BET Nitrogen adsorption technique.

Overview

Determination of specific surface area by the analysis of BET Nitrogen adsorption isotherms on mesoporous and macroporous materials with limited scope to microporous material below a pore diameter of 2nm

Applications and Benefits

Provides quantitative specific surface area information primarily for mesoporous and macroporous materials but also some semi-quantitative information on microporous materials with applications to medical devices, liquid and gas filtration, lime production, QC and QA in process control of specific surface area

Form of Results

Single point and multipoint BET specific surface area in units of m2/g, adsorption isotherm plot in the BET range, linearised BET transform plot, tabulated isotherm and BET data and BET constant.
