Measurement of special nanoparticle structures by light scattering

Characterization of nanoparticles beyond spheres is a topic of growing importance. Philip Wyatt, founder and CEO of Wyatt Technology, presents an extension and simplification of the traditional Rayleigh-Gans theory behind multi-angle light scattering to address nanoparticles of varying structures, including rods, tubes, ellipsoids, rings and superellipsoids.

Wyatt Technology is the recognized leader in light scattering instrumentation and software for determining the absolute molar mass, size, charge and interactions of macromolecules and nanoparticles in solution.

Wyatt's line of multi-angle static light scattering products couple to size exclusion chromatography (SEC-MALS), field-flow fractionation (FFF-MALS), and stop-flow composition-gradient systems (CG-MALS). Our dynamic light scattering (DLS) products operate in traditional cuvette as well as on-line and automated, high-throughput modes. We also offer unique instruments for electrophoretic light scattering (MP-PALS), differential refractometry, and differential viscosity.
