BET

The BET (Brunauer-Emmett-Teller) method is a widely employed technique in particle characterization for determining the specific surface area of porous materials. It is based on the physical adsorption of gas molecules onto the sample surface, and by analyzing the amount of adsorbed gas at different pressures, the surface area can be calculated using the BET equation. The BET method provides valuable insights into the porosity, texture, and surface properties of materials, making it essential in fields such as catalyst development, pharmaceuticals, and materials science.
