Viscotek Shows Advanced Technologies for Polymer, Proteins and Nanomaterials Characterization at ACS Fall Meeting 2009


07 August 2009: Malvern, UK: Viscotek, a Malvern company, is exhibiting its advanced technologies for characterizing natural and synthetic polymers, copolymers, biopolymers, proteins and nanomaterials at the American Chemical Society's Fall Meeting 2009 (August 16-20, 2009; Washington, DC, USA). These include the TDAmax(TM) gel permeation chromatography/size exclusion chromatography (GPC/SEC) system, which features an integrated triple or tetra detector array. As part of this setup, the recently introduced photo diode array (PDA) detector captures absorption spectra across the UV-vis wavelength range, delivering a fingerprint of each 'time slice' of the sample as it elutes from the column.

GPC/SEC is a chromatographic technique that separates natural and synthetic polymers, biopolymers and nanoparticles on the basis of size. When coupled with advanced detectors a range of additional parameters can be determined. Viscotek GPC/SEC technology provides absolute molecular weight, molecular size (Rg and Rh) and intrinsic viscosity as well as information on structure, conformation, aggregation, branching, copolymer and conjugate composition. Delivering a wealth of information from a single experiment, Viscotek's proprietary technologies encompass:

o Advanced column technology for an extended range of applications
o Low Angle Light Scattering (LALS) that delivers absolute molecular weight without the need for extrapolation, correction, assumptions or data fits
o Digital transducer viscometer technology which improves data accuracy, precision and resistance to corrosive solvents
o Photo diode array technology for multi-dimensional GPC/SEC analysis

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. www.malvern.com
