What Other Methods Exist for Surface Area Measurement?
Apart from the BET method, other techniques include Mercury Intrusion Porosimetry, which is useful for measuring pore sizes and volumes, and Small Angle X-ray Scattering (SAXS), which provides information on the surface area and structure of nanoparticles. Thermogravimetric Analysis (TGA) can also be used for certain materials to determine the surface area through weight changes upon heating.
