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:
- Not stated
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study with acceptable restrictions
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- Particle size investigated using laser diffraction technology.

- Percentile:
- D10
- Mean:
- 0.2 µm
- Remarks on result:
- other: standard deviation information not provided
- Percentile:
- D50
- Mean:
- 2.1 µm
- Remarks on result:
- other: standard deviation information not provided
- Percentile:
- D90
- Mean:
- 6.7 µm
- Remarks on result:
- other: standard deviation information not provided
- Conclusions:
- Under the conditions of this study the D50 was 2.1 µm, D10 was 0.2 µm and D90 was 6.7 µm.
- Executive summary:
The analysis was carried out on a Microtrac S3500 which uses laser diffraction technology. An amount of detergent (TSPP 5 %) was added to improve the distribution of the material in the solvent distilled water. The suspension of the material was treated ultrasonically to destroy potential agglomerates. Particle size determination was conducted in triplicate and the average taken.
Under the conditions of this study the D50 was 2.1 µm, D10 was 0.2 µm and D90 was 6.7 µm.
