Results and discussion
- Remarks on result:
- not measured/tested
Particle size
- Key result
- Percentile:
- D50
- Remarks on result:
- other: Particle Size measurement is not applicable!(migrated from fields under 'Mass median diameter' as D50 percentile. No source field for Standard deviation.)
Any other information on results incl. tables
The particle size measurement could not be performed because the sample is hygroscopic. The scanning electron microscope operates in high vacuum with an electron beam. Upon impact of the electron beam, the sample sublimates immediately. Thus a recording and evaluation of the imaging of the sample is not possible. The sublimation of the sample was exemplarily documented after 22 hours with light microscopy.
Applicant's summary and conclusion
- Conclusions:
- The particle size measurement could not be performed because the sample is hygroscopic.
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.
