- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- April 23, 2014
- Reliability:
- 1 (reliable without restriction)

- Principles of method if other than guideline:
- The test was performed according to the SOP - STR 071 protocol.
Laser light scattering. The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measures the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. - GLP compliance:
