Malvern Exhibits Viscotek Chromatography Solutions at ACS Spring Meeting
(Nanowerk News) Malvern Instruments will exhibit the TDAmax™ gel permeation chromatography/size exclusion chromatography (GPC/SEC) system from Viscotek, a Malvern company, at the American Chemical Society’s Spring 2009 National Meeting & Exposition. The theme for the meeting is ‘Nanoscience: Challenges for the Future’ and is being held from 22 – 26 March, Salt Lake City, UT, USA.
GPC/SEC is a chromatographic technique that employs specialized columns to separate natural and synthetic polymers, biopolymers and nanoparticles on the basis of size. When GPC/SEC is coupled with advanced detectors a range of additional parameters can be determined, including intrinsic viscosity, molecular size, and long chain branching.
The TDAmax gel permeation chromatography/size exclusion chromatography (GPC/SEC) system from Viscotek
The TDAmax is a comprehensive GPC/SEC system with an integrated triple or tetra detector array.
Launched at Pittcon, a new photodiode array (PDA) detector for the system provides a powerful and flexible tool for the rapid analysis of both polymers and biological macromolecules. Its many applications include identifying protein conjugates and complexes, aggregation and stability, and determining concentration ratios. By capturing absorption spectra across the UV-vis wavelength range, the new PDA detector provides a fingerprint of each ‘time slice’ of the sample as it elutes from the column. Measurement times are just 30 to 40 minutes, making the system highly productive. www.viscotek.com
Viscotek, a Malvern company, is market leader in advanced chromatography (GPC/SEC), offering complete systems for protein molecular weight, size and aggregation measurements, and synthetic polymer molecular weight and distribution. Its dilute solution viscosity (DSV) instrumentation, for example, provides manual and automated solutions for polymer characterization. Triple and Tetra GPC detectors enable absolute molecular weight measurement without calibration, an online PhotoDiode Array Detector permits chemical identification, and HT-GPC solutions provide for High-Temperature GPC of polyolefins and other synthetic polymers.
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.
