Recent Advances in Macromolecular Characterisation: DLS and Multidetection SEC

6th-10th May 2013

We would like to thank all who attended our recent seminar “Comprehensive Molecular Characterisation using Quadruple Detection Size Exclusion Chromatography” hosted in most major cities around Australia.

Size Exclusion Chromatography (SEC), also known as Gel Permeation Chromatography (GPC), is a very popular analytical tool for characterising synthetic and natural macromolecules. In its conventional and simplest form it only provides relative analysis. However with the addition of advanced detection technologies one can obtain a comprehensive array of molecular parameters including absolute molecular weights, molecular size, molecular density/intrinsic viscosity, and perform structural, conformational and compositional analyses.

In this presentation the concept of Quadruple Detector SEC method, a combination of Refractive Index, UV Photodiode Array, Light Scattering and Molecular Density/Solution Viscosity detectors, was discussed and various cases of protein, bio-polymer and synthetic polymer characterisation were explored.
