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.
