Frederic Violleau Ph.D., Professor in the School of Engineering at the University of Toulouse, discovered Wyatt instrumentation over 15 years ago, having first been introduced to the technology using a DAWN® DSP. A few years later his lab completed their instrument suite by investing in an Eclipse® II AF4 system coupled with a DAWN® multi-angle light scattering instrument and Optilab® RI detector. This investment made his lab one of the first French university laboratories equipped with Wyatt technology.

Some of his early research was focused on the characterization and study of the properties of macromolecules and polysaccharide, before diversification towards nanoparticles, self-assembly systems and monoclonal antibody analysis. In 2012, Violleau was a visiting researcher at the Advanced Separation Technologies Laboratory at the Colorado School of Mines, and from that experience, created the Toulouse FFF Center, a unique analytical platform in Europe, integrating all existing FFF techniques.

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.
