The Solution is Light! Wyatt Technology is the world leader in light scattering instrumentation for characterizing macromolecules and nanoparticles in solution. Wyatts products determine absolute molecular weight, size, charge, interaction properties, conformation and conjugation. The company offers a complete family of multi-angle light scattering (MALS) detectors for size exclusion chromatography (SEC) as well as field-flow fractionation (FFF), and the only MALS detectors for UHPLC. In addition, Wyatt produces high-sensitivity refractive index and viscometry detectors for SEC/GPC, automated dynamic light scattering (DLS) systems for use with standard well plates, zeta potential instruments that can be automated, and, finally, composition gradient techniques for biomolecular interaction analyses.
