Materials and methods
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: ECHA Guidance Chapter R.7A, R7.1.14 Grnulometry, Table R.7.1-31
- Deviations:
- not specified
- Principles of method if other than guideline:
- Method: Laser scattering/diffraction
In general, the scattering of the incident light gives distinct pattern which are measured by a detector. This technique is particle property dependetnt – i.e. material has unique scattering and diffraction properties which are also particle size dependent. Laser scattering techniques are suitable for geometric particles, viz spheres, cubes and monocrystals. Particle size will be established optically.
Measure Instrument: GSL-101BI Laser Particle Size Distribution Analyzer - GLP compliance:

- Type of method:
- Laser scattering/diffraction
- Type of distribution:
