EC number: 943-688-6 | CAS number: -
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
- 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:
- In order to measure the particle size distribution, the technique of laser diffraction (laser light scattering) was used by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analysed to calculate the particle size distribution based on the scattering pattern.
- GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of distribution:
- volumetric distribution
- Mass median aerodynamic diameter:
- ca. 24.713 µm
- Remarks on result:
- other: after ultrasonic treatment (2 min)
- Key result
- Percentile:
- D50
- Mean:
- 24.713 µm
- Remarks on result:
- other: after ultrasonic treatment (2min)
- Percentile:
- D10
- Mean:
- 11.101 µm
- Remarks on result:
- other: after ultrasonic treatment (2min)
- Percentile:
- D90
- Mean:
- 52.492 µm
- Remarks on result:
- other: after ultrasonic treatment (2min)
- Conclusions:
- Mass Median Diameter value is 24.713 µm
- Executive summary:
