- Executive summary:
The determination of particle size distribution was carried out in accordance with the International Standard ISO 13320-1 and following the Principles of GLP. It was performed passing a laser through a test substance suspension and measuring the light scattered at different angles by a multi-element detector. The mass moment mean (De Brouckere Mean Diameter) of the tested material is determined to be 70.32 µm and the percentiles of particle size are: d10= 9.492 µm, d50= 55.35 µm, and d90= 120.08 µm.
