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, 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Reason / purpose for cross-reference:
- reference to same study
- 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:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Percentile:
- D10
- Mean:
- ca. 1.427 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Percentile:
- D50
- Mean:
- ca. 29.777 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Percentile:
- D90
- Mean:
- ca. 93.092 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Conclusions:
- MD10 = 1.427 µm;
MD50 = 29.777 µm;
MD90 = 93.092 µm. - Executive summary:
Methods:
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 = 1.427 µm
MD50 = 29.777 µm
MD90 = 93.092 µm
Reference
The analysis has been run after 2 minutes of ultrasonic treatement.
Description of key information
MD10 = 1.427 µm
MD50 = 29.777 µm
MD90 = 93.092 µm
