Particle Size Distribution

Why can the determination of the Particle Size Distribution (PSD) be challenging?

The PSD is required for a number of regulatory purposes:

• granulometry for the REACH dossier of solid substances (OECD 110)
• REACH substance identity profile (sameness) for Nanomaterials
• the definition of nanoforms
• analytical determination of nano materials in genotoxicity or ecotoxicological studies

The smaller the particles are, the more elaborate the techniques have to be. LAUS has equipped a new lab with state-of-the-art technology and trained a highly qualified study director. We have developed a deeper understanding on how to approach the different substance types (e. g. nanomaterials) and how to receive comprehensive results. Sometimes complementary techniques like SEM/TEM, XRD with Rietveld or BET are required to describe a substance in its entity.
