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:
- April 22, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- Principles of method if other than guideline:
- The test was performed according to the internal method SOP-STR 071 (Hydro 2000S) corresponding to the Laser light scattering procedure.
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:
- D50
- Mean:
- ca. 86.256 µm
- Remarks on result:
- other: Analyzed after 2 minutes of ultrasonic treatment.(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
- Percentile:
- D10
- Mean:
- ca. 28.897 µm
- Remarks on result:
- other: Analyzed after 2 minutes of ultrasonic treatment.
- Percentile:
- D90
- Mean:
- ca. 181.774 µm
- Remarks on result:
- other: Analyzed after 2 minutes of ultrasonic treatment.
- Conclusions:
- The substance has the Mass Median Diameter of 86.256 µm.
- Executive summary:
Method:
The test was performed according to the internal method SOP-STR 071 (Hydro 2000S) corresponding to the Laser light scattering procedure.
Results:
The tested substance has the Mass Median Diameter of 86.256 µm.
