Applicant's summary and conclusion
- Conclusions:
- A particle size mono-modal distribution with X50 (Dv50) of 24.5 microns was obtained.
- Executive summary:
The particle size of a sample of Escherichia Coli dehalogenase catalyst was determined by laser diffraction. X10, X50 and X90 values of 10µm, 24µm and 57µm respectively were obtained with a mono-modal distribution with X50 (Dv50) of 24.5 µm.
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.
