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:
- March 17, 2015
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Laser light scattering. The test was performed according to the SOP - STR 071 Ed. 01 (Hydro 2000S-A) protocol.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure 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:

- Percentile:
- D10
- Mean:
- ca. 9.455 µm

- Conclusions:
- MD10 = 9.455 µm
MD50 = 59.509 µm
MD90 = 209.972 µm - Executive summary:
Method:
The substance has been tested for granulometry by the volumetric distribution.
The particle size distribution was analyzed using the Mastersizer 2000 tool, which uses the technique of laser diffraction to measure 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.
Result:
MD10 = 9.455 µm
MD50 = 59.509 µm
MD90 = 209.972 µm
Reference
The analysis has been run after 2 minutes of sonification.
Description of key information
MD10 = 9.455 µm
MD50 = 59.509 µm
