The measurement of the specific surface area of a sample is made from an isotherm obtained by nitrogen adsorption/desorption volumetry at 77K.
The specific surface is expressed in m2/g of the sample after degassing from the BET method.
The implementation of the t-plot and BJH methods allows an estimation of the porosity of the sample and its distribution (between 8 and 800 Å of opening).
