Description of key information
Particle size distribution was determined according to CIPAC MT 187. L10D: 10.9 µm. L50D: 32.7 µm, L90D:78.9 µm
Additional information
For the determination of the particle size distribution a Malvern Mastersizer 2000 with the scirocco 2000 measuring cell was used. The well mixed sample was introduced into a monochromatic Helium. Neon laser beam. The large particles in the sample scattered the laser beam into small angles of scatter and small particles scattered the laser beam into larger angles of scatter. Depending on the individual angels of scatter the scattered laser beam was detected in different areas of the detector. From this light energy measured on different parts of the detector and a mathematical conversion the volume based particle size distribution was calculated. Particle size distribution was determined according to CIPAC MT 187.
L10D: 10.9 µm. L50D: 32.7 µm, L90D:78.9 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.
