Dimensional analysis of to evaluate the size of...

The Mastersizer 2000 uses the technique of laser diraction to measure the size of particles. It does this by measuring the intensity of light scattered as a laser beam passes through a dispersed particulate sample. This data is then analyzed to calculate the size of the particles that created the scattering pattern. This instrument is equipped by Hydro 2000MU and Scirocco 2000: the rst one is a large volume manual wet sample dispersion unit designed for use with standard laboratory beakers, while the second is an automated dry powder dispersion unit for particle size analyses. The Mastersizer permits the granulometric characterization of all that is in powder form, from pharmaceutical powder to our or milk powder, or again cosmetic powder as face powder, blush and eye shadow. It provides information about the average size of the particles, the volume of dust characterized by a specic average diameter and the distribution of particle size. Know this information is important because the particle size aects the smoothness of the powder and thus it inuences important industrial processes such as lling of the jar, making compact or tablet.
