- Study period:
- 22 December 2009-03 February 2010
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Study has been performed according to ISO, CIPAC and OECD guidelines and according to GLP principles.
- Qualifier:
- according to guideline
- Guideline:
- other: BS ISO 13320-1:1999
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: CIPAC MT 187
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- Laser scattering/diffraction
- Remarks:
- The analysis was carried out using the Dry Powder Module. The sample was analysed using the Malvern Mastersizer 2000 laser Diffraction Analyser
- Type of distribution:
- other: laser diffraction particle size analysis
- Percentile:
- D50
- Mean:
- 23.292 µm
- Remarks on result:
- other: Migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.
- Percentile:
- D10
- Mean:
- < 7.206 µm
- St. dev.:
- 0.158
- Percentile:
- D50
- Mean:
- < 11.933 µm
- St. dev.:
- 0.078
- Percentile:
- D90
- Mean:
- < 19.206 µm
- St. dev.:
- 0.26
- Conclusions:
- Using the laser diffraction test (with the Dry Powder Module), the Mass Median Aerodynamic Diameter (MMAD) of the test substancewas determined to be 23.292 µm.
Reference
32.84% by volume of sample was seen to be < 10.00 µm.
Description of key information
Using the laser diffraction test (with the Dry Powder Module), the Mass Median Aerodynamic Diameter (MMAD) of the test substancewas determined to be 23.292 µm.
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
