An Introduction to BET Surface Area Measurement 

In this video we present the calculation of BET surface area from gas adsorption isotherms. We start by looking at the adsorption process and mono-layer formation during a nitrogen adsorption analysis and then we explore the BET region of the isotherm. We present the BET equation in terms of the theory behind it and then the practical application of it to calculate the BET surface area of a real sample.
