The BET method for microporous materials
5 Sept 2025The Brunauer-Emmett-Teller (BET) method is the most common method for the evaluation of specific surface areas. In material science, taking accurate surface area measurements is critical but using BET can often lead to distorted due to micropores. Traditional approaches often overlook key nuances in Type I isotherms, complicating analysis and interpretation.
Discover how advanced validation techniques, including the Rouquerol criteria can enhance BET analysis to offer greater precision and reliability in microporous material characterization.

Particle CharacterizationParticle characterization instruments are used to determine particle size distribution, shape, surface area, zeta potential, density and porosity of particles and materials. Multiple tecchniques are available for determining particle size, shape and count including dynamic light scattering (DLS), laser diffraction, electrozone (Coulter technique), imaging particle analysis and single particle optical sensing. Determine the density of your material with a gas pycnometer or examine its surface area and porosity with gas adsorption analyzers and mercury porosimeters.
