Particle size distribution (Granulometry)
Administrative data
Link to relevant study record(s)
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- December 27th, 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Principles of method if other than guideline:
- Laser light scattering. The test was performed according to the SOP - STR 071 protocol.
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 measures 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:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D50
- Mean:
- 48.374 µm
- Remarks on result:
- other: Analysis carried out after 2 minutes of ultrasonic treatment.
- Percentile:
- D10
- Mean:
- 1.753 µm
- Remarks on result:
- other: Analysis carried out after 2 minutes of ultrasonic treatment.
- Percentile:
- D90
- Mean:
- 193.05 µm
- Remarks on result:
- other: Analysis carried out after 2 minutes of ultrasonic treatment.
- Conclusions:
- d(0.5): 48.374 µm
