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:
- 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:
- The analysis was carried out on a Sedigraph III 5120, which uses sedimentation technology. A suspension of material, detergents (TSPP and Tamol) and distilled water was treated ultrasonically to destroy potential agglomerates. This suspension was pumped into the measuring cell. The gravity and particle size affect sedimentation which was determined by x-rays.
- GLP compliance:
- not specified
- Type of method:
- sedimentation (gravitational settling)
- Percentile:
- D50
- Mean:
- 0.3 µm
- Remarks on result:
- other: standard deviation not reported
- Percentile:
- D90
- Mean:
- 1.4 µm
- Remarks on result:
- other: standard deviation not reported
- Percentile:
- other: D20
- Mean:
- 0.2 µm
- Remarks on result:
- other: standard deviation not reported
- Conclusions:
- Under the conditions of this study the D50 was 0.3 µm, D20 was 0.2 µm and D90 was 1.4 µm.
- Executive summary:
The particle size distribution of the test material was investigated using sedimentation technology.
Under the conditions of this study the D50 was 0.3 µm, the D20 was 0.2 µm and the D90 was 1.4 µm.
