Characterization of Chitosans using Asymmetrical Flow Field-Flow Fractionation and Multi-Angle Light Scattering

Published on

Tags: chitosan, Flow Field-Flow Fractionation

Christian Augsten, Karsten Mäder

Flow Field-Flow Fractionation (Flow-FFF) is a powerful tool to separate molecules and particles in a range from 103 to 107Da and particles of nanometric size up to a few micrometers [1]. By coupling FFF to Multi-angle light scattering (MALS) it is possible to determine absolute molar masses (M) of molecules and to verify their aggregation. For macromolecules of an appropriate size the radius of gyration (rg) can be achieved [2]. The aim of our study was to investigate various chitosan types by applying Flow-FFF and MALS to their aqueous solutions.
