Applicant's summary and conclusion
- Conclusions:
- The mass median diameter of the volumetric particle size distribution is 27.1 µm.
- Executive summary:
The volumetric particle size distribution of the substance was determined according ISO 13320 - 1 with a Malvern Mastersizer 2000 equipment using the vibrating tray unit Scirocco 2000. The mass median diameter D50 was found to be 27.1 µm.
