Volume specific surface area (VSSA) of powders

Determination of volume-specific surface area (VSSA) for the identification of nanoparticles.

VSSA can be calculated from the specific surface area obtained by N2 adsorption and the BET method and effective density obtained by He Pycnometry.

The measurement is a part of the EC recommendation for the definition of nanomaterials (2022/C229/01).
