Particle Sizing in the Submicron Range by Dynamic Light Scattering

Abstract

The application of dynamic light scattering for the determination of particle size distributions in the submicron range is reviewed. First, the basic principles and assumptions used in this application are presented. The practical performances are illustrated with results obtained from round-robin studies. A short comparison with particle sizing by static light scattering is included. Finally, new developments for on-line or in-situ characterization of concentrated and opaque dispersions are briefly presented.
