How to use N2 and Kr gas adsorption isotherms to calculate BET Surface Area

We use gas sorption software to show you how to fit BET transform data to a nitrogen adsorption isotherm to calculate BET Surface area. We then show you a poor quality nitrogen adsorption isotherm of a low surface area sample and compare it to a krypton adsorption isotherm. This shows how useful krypton adsorption isotherms are when we analyse very low surface area materials
