PARTICLE SIZING BY QUASI-ELASTIC LIGHT-SCATTERING

The application of quasi-elastic light scattering for the determinatio n of particle size distributions is reviewed. The basic principles and assumptions on which the method relies are presented on an introducto ry level. The practical performances are illustrated by different resu lts including results obtained by round-robin comparative studies. Fin ally, new developments for on-line or in situ characterization of conc entrated and opaque dispersions are briefly presented.
