bet (brunauer emmett teller) analysis

How Does BET Analysis Work?

The BET method involves measuring the amount of gas adsorbed onto the surface of a material at different pressures. Typically, nitrogen gas is used. The data obtained is then plotted to create a BET isotherm, from which the surface area can be computed. The process usually involves the following steps:
Preparation of the sample by degassing
Adsorption of a gas at liquid nitrogen temperature
Recording the adsorption data
Applying the BET equation to determine the surface area
