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:
- October 10, 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods
- 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. 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 laserbeam 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. 41.771 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatment
- Percentile:
- D10
- Mean:
- ca. 4.311 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatment
- Percentile:
- D90
- Mean:
- ca. 173.109 µm
- Remarks on result:
- other: after 2 minutes of ultrasonic treatment
- Conclusions:
- The Median Mass Diameter, MMD, is 41.771 µm
- Executive summary:
The granulometry of the substance was tested by laser light diffraction. The test substance has a mean mass diameter, MMD, of 41.771 µm
