Malvern Instruments's online web seminar series introduces triple-detection techniques for size-exclusion chromatography/gel-permeation chromatography (SEC/GPC).
The web-based seminars are suitable 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, kicks off on 16 July 2009 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 audiences at Malvern's website.
GPC/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.
