Characterising macromolecules with GPC / SEC using OMNISEC

Malvern Instruments

Manufacturers and researchers making gelling agents in food have to isolate and identify polysaccharides with particular molecular properties.

A widely used technique, GPC / SEC characterises a range of macromolecules, from bulk manufactured materials to natural polymers and proteins. The technique can be used to measure molecular weight moments, dispersity, intrinsic velocity, and hydrodynamic radius of macromolecules.

Download this free whitepaper to find out more about the use of GPC / SEC, including a brief overview of the technique mechanics, alongside application data showing the benefits of the technique in comparison to conventional methods.
