Sponsoring international separations symposium
Viscotek has announced its sponsorship of SCM-3 - the Third International Symposium on Separation and Characterisation of Natural and Synthetic Macromolecules
Due to take place at the Rhone Congress Centre (Amsterdam, Netherlands) from 31 January to 2 February 2007, the important symposium will bring together a variety of scientists who share an interest in the separation and characterisation of large molecules.
Bringing together specialists from the analytical chemistry, polymer science and life science communities, the SCM-3 programme will feature plenary lectures by internationally renowned speakers, keynote lectures, a topical program of oral presentations plus an exhibition of related instruments and consumables.
At this important meeting Viscotek will display its market leading triple detector array (TDA) and popular GPCmax systems.
Viscotek says the TDA sets the standard for GPC/SEC technology and is the preferred method for characterising natural and synthetic macromolecules.
The TDA employs a concentration detector, viscometer and light scattering detector acting in concert, with each detector providing complimentary but different information.
In a single GPC/SEC experiment using the TDA users can obtain absolute molecular weight, molecular size, intrinsic viscosity, conformation and molecular structure information.
The GPCmax is the world's first integrated pump, autosampler and degasser module specifically designed for GPC/SEC applications.
It mates seamlessly with Viscotek's triple detector array or a simple concentration detector to form a complete GPC/SEC system.
With offices in the UK, Netherlands, Germany and France, Viscotek claims to be Europe's leading provider of complete solutions for macromolecular characterisation to the chemical, pharmaceutical and biotech industries.
Also Viscotek has chosen SCM-3 to launch a ground breaking new generation of its popular model 802 dynamic light scattering (DLS) instrument - the model 802DAT.
Traditionally laboratories faced with analysing higher concentration samples, such as emulsions or nanoparticles, have found traditional light scattering instruments limited both in terms of sensitivity and resolution.
To address these deficiencies Viscotek developed 'dual attenuation technology' as an option for its new generation system.
Dual attenuation technology (DAT) is a technique that controls the level of light entering the sample as well as controlling scattered light going to the detector.
In this way, for the first time, researchers are able to work at the optimum conditions for the laser and detector irrespective of sample type.
Designed for laboratories that need a complete understanding of how their natural or synthetic macromolecule behaves in solution the model 802DAT sets a new standard for superior sensitivity, resolution, accuracy and sampling versatility compared to any other light scattering instrument currently available, says the company.
Viscotek has published application notes illustrating the extended capabilities of gel permeation chromatography/size exclusion chromatography (GPC/SEC) using the PDA detector for the TDAMax system.
Viscotek will show products for characterising polymers, copolymers, biopolymers, proteins and nanomaterials at the American Chemical Society's (ACS's) Fall Meeting on 16-20 August in Washington DC.
Viscotek, a Malvern company, will exhibit and host a seminar at the fourth International Symposium on the Separation and Characterization of Natural and Synthetic Macromolecules (SCM-4).
Viscotek's DSV system automates the temperature-controlled measurement of polymer dilute solution viscosity (DSV), a parameter used for molecular weight determination.
Viscotek has published a technical article that describes how High Temperature GPC/SEC allows scientists to determine the molecular weight and branching structure of polyolefins.
