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:
- 22 April 2014 to 11 September 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 187
- Deviations:
- no
- GLP compliance:

- Specific details on test material used for the study:
- Test substance: FAT 40075/D
Batch Number: BS-1113243 - Percentile:
- D10
- Mean:
- 1.9 µm
- Remarks on result:
- other: Std deviation not specified
- Key result
- Percentile:
- D50
- Mean:
- 5.77 µm
- Remarks on result:
- other: Std deviation not specified
- Percentile:
- D90
- Mean:
- 12 µm
- Remarks on result:
- other: Std deviation not specified
- Conclusions:
- The mass median diameter was found to be 5.77 µm.
- Executive summary:
The particle size distribution of FAT 40075/D was determined according to CIPAC MT 187 by laser diffraction method with dry dispersion. Malvern Mastersizer 2000 was used for determination of particle size distribution. An appropriate amount of the particles of the test item were introduced to the analyser beam (Helium-Neon Laser) by direct spraying through the measurement area using the dry powder feeder. By altering the air pressure and feeding rate the optimum measuring conditions were found. The dispersing energy was chosen in a way that the particle size distribution was nearly constant with increasing energy. The particle size distribution was determined twice and the average result is given. Based on the findings of the study, the mass median diameter was found to be 5.77 µm whereas L10D and L90D were 1.90 and 12.0 µm, respectively.
