Specific surface area analysis

Specific surface area analysis measures the total surface area available per unit mass of a material, generally expressed in m²/g. This data is essential for understanding the adsorption, reactivity or dissolution properties of powders and porous materials. It plays a crucial role in various sectors such as nutraceuticals, technical ingredients, materials, catalysts and environmental adsorbents.

The most common method is gas adsorption using the BET (Brunauer–Emmett–Teller) technique, which is based on the adsorption of nitrogen at cryogenic temperatures. The analysis also allows, in some cases, the determination of pore size distribution and porosity. A high specific surface area can indicate better functional efficiency, particularly for active powders or filter materials.

Commonly analyzed matrices: plant extracts, functional powders, silicas, clays, activated carbons, biomaterials, micronized ingredients, etc.

At YesWeLab , we collaborate with a rigorously selected network of laboratories, most of which are certified and/or accredited (ISO 17025, COFRAC, etc.). These laboratories are chosen based on your specific needs, the matrices to be analyzed, and the analytical techniques or methods required.
