From technology overview to focused applications - Malvern's chromatography web seminars deliver practical guidance

(Nanowerk News) 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 characterizing natural and synthetic polymers and proteins, kicks 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 characterization. The web seminars are presented by technical and applications specialists from Viscotek, a Malvern company, and registration is free to worldwide audiences.
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 characterized 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 characterization.
About Malvern Instruments
Malvern Instruments provides a range of complementary materials characterization tools that deliver inter-related measurements reflecting the complexities of particulates and disperse systems, nanomaterials and macromolecules. Analytical instruments from Malvern are used in the characterization of a wide variety of materials, from industrial bulk powders to nanomaterials and delicate macromolecules. A broad portfolio of innovative technologies is combined with intelligent, user-friendly software. These systems deliver industrially relevant data enabling our customers to make the connection between micro (such as particle size) and macro (bulk) material properties (rheology) and chemical composition (chemical imaging).
Particle size, particle shape, zeta potential, molecular weight, chemical composition and rheological properties measurements are now joined by advanced chromatography solutions (GPC/SEC), extending Malvern’s technologies for protein molecular weight, size and aggregation measurements, and synthetic polymer molecular weight and distribution. The company’s laboratory, at-line, on-line and in-line solutions are proven in sectors as diverse as cement production and pharmaceutical drug discovery.
Headquartered in Malvern, UK, Malvern Instruments has subsidiary organizations in all major European markets, North America, China, Korea and Japan, a joint venture in India, a global distributor network and applications laboratories around the world.
