TIME-RESOLVED, STATIC LIGHT-SCATTERING - NEW POSSIBILITIES IN POLYMER CHARACTERIZATION

We have developed a highly sensitive, multi-angle, static light scattering (TRSLS = time resolved static light scattering) instrument, which measures the angular dependent Rayleigh scattering intensity of solutions simultaneously at 38 angles within approximately one second. It is thus suitable as a quick and easy to use static light scattering device for routine polymer and colloid characterization. The time resolution allows the kinetics of many systems to be investigated down to a second time scale, such as polymerization kinetics of linear, branched and crosslinked polymer structures, thermoreversible gelation, growth of colloidal particles, structural changes in micellar systems, etc.
