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:
- June 23, 2015
- 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:
- The test has been conducted according to internal method SOP-STR 071 (Hydro 2000S) corresponding to the laser light scattering procedure.
The particle size distribution was analysed 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 analysed 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. 28.639 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Percentile:
- D10
- Mean:
- ca. 16.078 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Percentile:
- D90
- Mean:
- ca. 49.451 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatement
- Conclusions:
- The substance has a Median Mass Diameter of 28.639 µm.
- Executive summary:
Method:
