The Particle size distributions analysis has been made with the aid of a MALVERN MASTERSIZE mod MS2000.
On passing an expanded monochromatic laser beam through a dry sample in a non-reactive liquid, the light is diffracted and a diffraction image with radial symmetry is produced on the focal plane of the lens.
The intensity of the light rings is directly proportional to the number of particles seen with the beam of light and the radius of the rings is inversely proportional to the diameter of the particles.
The process of sample measurement involves recording the scattering pattern produced as the sample passes through the path of the laser. An initial background measurement captures scattering from the cell windows, any contaminant present and, in the case of wet measurement, the pure dispersant.
The sample is dispersing at propan-2-ol and placed in Hydro 2000 SM accessory - GLP compliance:

Applicant's summary and conclusion
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.
