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:
- July 24th, 2015
- Reliability:
- 2 (reliable with restrictions)
- 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 Ed. 03 (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:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 13.886 µm
- Remarks on result:
- other: after 2 minutes of sonification.
- Percentile:
- D50
- Mean:
- ca. 37.98 µm
- Remarks on result:
- other: after 2 minutes of sonification.
- Percentile:
- D90
- Mean:
- ca. 73.444 µm
- Remarks on result:
- other: after 2 minutes of sonification.
- Conclusions:
- MMD = 37.98 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.
Results:
MD10 = 13.886 µm
MD50 = 37.980 µm
MD90 = 73.444 µm
