BET surface area analysis of activated carbon

About

The BET surface area method is based on a 1938 paper by Brunauer, Emmett and Teller, to measure the internal surface area of activated carbon. The mathematical model uses the nitrogen adsorption isotherm at low temperature and single layer adsorption.

BET measuring instrument

The DESOTEC R&D laboratory is equipped with a BET measuring instrument that calculates the internal surface area as well as the average pore size, pore volume and pore size distribution. Depending on the application, DESOTEC can offer activated carbon types ranging from 400 to more than 1,500m2/g.
