Wyatt Technology Corporation (WTC) is involved in the research and development of techniques, instrumentation and software for absolute macromolecular and nanoparticle characterization. Founded in 1982 by Dr. Philip J. Wyatt, the company was formed around his patents, ideas and inventions in industrial, military, and medical domains and commercialized the first light scattering instrumentation using lasers. To date, WTC has developed the following instruments: classical multi-angle light scattering detectors for determining absolute molecular weights and sizes of proteins, polymers, biopolymers and nanoparticles in solution, differential refractometers, differential viscometers, dynamic light scattering instruments, zeta potential instruments, composition-gradient apparatus, as well as field-flow fractionation separation systems and their software.
