Specific surface area of powders and porous solids

Determining the specific surface area of powders and solids is of great importance in various industries as it directly influences the reactivity, adsorption capacity and catalytic efficiency of the material. A larger specific surface area usually means more active sites for chemical reactions, which is important in areas such as pharmaceuticals, where the dissolution rate influences the effectiveness of drugs, or in catalysis, where the reaction rate depends on the available surface area. In addition, understanding the specific surface area helps with quality control and optimization of processing conditions in production, which improves the performance of the final product.

We determine the specific surface area using the 5-point BET method (Brunauer-Emmett-Teller) using nitrogen adsorption.
