More than four decades ago, Wyatt Technology's scientists invented the first commercial light scattering instruments incorporating lasers as their light source and have been organized since then around defining and redefining the state-of-the-art laser light scattering hardware, software, training and services to meet customer needs with several related technologies added to the firm's product line including dynamic light scattering, refractometry, viscometry, and field-flow fractionation. The scientific instrumentation developed and offered by Wyatt Technology in innovative light scattering space: instruments, accessories, software and services is used in the determining the properties of macromolecules and nanoparticles in solution. Wyatt's instruments measure Molar mass; Size; Charge or zeta potential; Biomolecular interactions and Conformation and composition. Wyatt provides cutting-edge solutions for on-line multi-angle static light scattering (SEC-MALS), field-flow fractionation (FFF-MALS), composition-gradient (CG-MALS), high-throughput and traditional dynamic light scattering (DLS), electrophoretic mobility via phase-analysis light scattering (MP-PALS), differential refractometry and differential viscosity. the firm's technology includes instruments and software for chromatographic and composition-gradient multi-angle static light scattering, high-throughput dynamic light scattering, field flow fractionation, differential refractometry, electrophoretic mobility and differential viscometry.
