Malvern will exhibit a multiple detection gel permeation chromatography (GPC) system and particle characterisation instruments at the upcoming American Chemical Society (ACS) exposition in Boston.
At the ACS Fall 2010 National Meeting and Exposition, which will be held on 22-26 August, Malvern will exhibit the Viscotek TDAmax multiple detection GPC system together with instruments from the Zetasizer particle characterisation range.
Visitors will be able to explore other systems from Malvern's range of complementary materials characterisation solutions through interactive displays.
Company specialists will be available throughout the show to advise on individual materials characterisation challenges.
Applications for the Viscotek TDAmax triple detector array (TDA) GPC system from have been extended through the inclusion of a viscometer in the setup.
The TDA maximises the productivity of GPC analysis by simultaneously measuring absolute molecular weight, molecular size and intrinsic viscosity.
The new viscometer combines excellent sensitivity with a 316 stainless-steel, chemical-resistant transducer construction.
It provides precise intrinsic viscosity and structural information for an expanded range of biomolecules and natural and synthetic polymers.
The viscometer design uses digital inert transducer technology to give a faster, more sensitive response to viscosity changes than traditional transducers.
Its 316 stainless-steel construction means that there are few limitations in terms of salt content or pH on the chromatographic conditions that can be used.
The TDAmax enables protein scientists to determine the degree of oligomerisation, aggregation, conformation and conjugation in protein samples.
For polymer scientists, it delivers information for sensitive product quality control and process optimisation.
Malvern's Zetasizer series includes systems that measure particle size, zeta potential and molecular weight.
The novel measurement technology and patented optics built into Zetasizer Nano systems, for example, make them equally applicable to characterising high-concentration colloids and nanoparticles of all types through to the measurement of dilute proteins and macromolecules in their native state.
