From Technology Overview to Focused Applications

Malvern Instruments online web seminar series introducing triple detection techniques for size exclusion chromatography/gel permeation chromatography (SEC/GPC) provides information for experts and beginners alike.

The series on SEC/GPC triple detection, which has become the preferred method for characterising natural and synthetic polymers and proteins, kicked off on 16th July with a basic overview. It continues monthly for the rest of the year with specific application examples covering both protein and polymer characterisation.

The web seminars are presented by technical and applications specialists from Viscotek, a Malvern company, and registration is free to worldwide audiences at http://www.malvern.com/webinar

Gel Permeation Chromatography (GPC), also known as Size Exclusion Chromatography (SEC), is a technique that employs specialised columns to separate natural and synthetic polymers, biopolymers and nanoparticles on the basis of size. As the sample is separated and elutes from the column, it can be characterised by a single concentration detector or series of detectors.

When the GPC/SEC separation is coupled with advanced detectors such as light scattering, viscometer and concentration detectors, it provides a distribution of absolute molecular weight and size, and intrinsic viscosity measurements, that together yield information on macromolecular structure, conformation aggregation and branching.

Malvern’s series of more than 120 web seminars in 2009 covers many different aspects of the company’s technologies and products for materials characterisation.
