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 27,2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study conducted according to internationally accepted testing procedures.
- Qualifier:
- according to guideline
- Guideline:
- ISO 13320 (Particle size analysis - Laser diffraction methods)
- Principles of method if other than guideline:
- Laser light scattering. 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 does this by measuring 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 particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Remarks on result:
- not measured/tested
- Percentile:
- D50
- Mean:
- ca. 20.797 µm
- St. dev.:
- 0
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Conclusions:
- Median Mass Diameter =20.797 µm
- Executive summary:
Direct Blue 80 has been tested for granulometry. The test item shows a median mass diameter of 20.797 µm
Reference
The analysis has been done after 2 minute of sonication
