Engineering Nanoparticle Coatings

Researchers working at NanoQAM, the nanotechnology research centre of the University of Quebec, are successfully innovating novel polymer coatings on the basis of data measured using a Viscotek high temperature gel permeation chromatography (HT-GPC) system from Malvern Instruments. The system is proving crucial for efficient polymer characterisation, reliably providing absolute molecular weight and structural information to support research goals. A dependable high temperature solution is a pre-requisite for the polymers under test, as it is for bulk polyolefins. Malvern has developed the Viscotek HT-GPC system specifically for polyolefin analysis. These polymers are only sparingly soluble, necessitating the use of high temperatures throughout the analytical cycle. The Viscotek HT-GPC provides a reliable, cost-effective solution for operation at temperatures up to 160oC. The full triple detector configuration delivers absolute molecular weight without extrapolation or correction, molecular size (Rg and Rh), intrinsic viscosity and branching information in a single GPC/SEC experiment.
