“Good value and excellent performance is a combination that will warm the heart of any academic polymer scientist,” said Professor Kenneth J Wynne of the Department of Chemical and Life Science Engineering at Virginia Commonwealth University, when asked about his 11-year use of Viscotek gel permeation chromatography systems from Malvern Instruments. Professor Wynne’s research team uses the Viscotek TDAmax triple detection system to carry out routine GPC when developing and applying novel surface modifications to polyurethanes and other polymers. Professor Kenneth J Wynne said, “The Viscotek TDAmax is extremely valuable because in our work on polymers we perform some syntheses which can lead to large molecules with two drastically different structures. GPC is critical in delineating the amounts of each structure – the Viscotek system we use employs quadruple detection that includes refractive index, light scattering at both 90 degrees and low angle, and viscosity detectors.”
