Heppe Medical Chitosan at Euchis 2009
From Mai 23 to Mai 26 the 9th EUCHIS will take place in Venice. Every other year the European Chitin Society offers the opportunity to researchers and companies to present their latest research results and application-developments related to chitin and chitosan. Heppe Medical Chitosan GmbH will be there, too. Participants should register before February 27.

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