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:
- comparable to guideline study
- Justification for type of information:
- Non GLP study. It was assessed that Laser scattering/diffraction method is suitable to determine the distribution of particles. No information about calibration of the instrument has been reported. Test item particle size result is in the applicability range of the method (0.1-100 microns).
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions - Method A: Particle Size Distribution (effective hydrodynamic radius)
- Version / remarks:
- The determination of the particle size distribution was determined by laser light.
The method used is analogous and therefore considered to be equivalent to USP <429>, Ph.Eur. 2.9.31. and to that described in section 5.2. of the OECD 110 Guideline concerning Determination of Particle Size Distribution. - GLP compliance:
- no
- Type of method:
- Laser scattering/diffraction
- Type of particle tested:
- primary particle
- Type of distribution:
- volumetric distribution
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch number of test material:
2012-000203
- Expiration date of the lot/batch:
07/02/2013, W0167
- Purity test date:
> 99.9%, 23/01/2011
INFORMATION ON NANOMATERIALS

10-100 nm; 78
- Specific surface area: 7.4293 ± 0.0132 m²/g - Percentile:
- D50
- Mean:
- 0.691 µm
- Remarks on result:
