Characterisation of Polymers, Proteins, Biomolecules and Nanoparticulate Materials

Analytica 2008 has been selected by Viscotek as the venue to unveil its latest technological and applications advances for multi-detector characterisation of polymers, proteins, biomolecules and nanoparticulate materials. Visitors to the Viscotek exhibit on Booth 383, Hall A1 will be able to see and discuss, with technical specialists, a new generation of the popular Model 802 Dynamic Light Scattering (DLS) instrument - the Model 802DAT. Traditionally laboratories faced with analysing higher concentration samples, such as protein crystallography scientists, protein NMR scientists, emulsions or nanoparticle researchers, have found traditional light scattering instruments limited both in terms of sensitivity and resolution. To address these deficiencies Viscotek developed as an option for its new generation system - Dual Attenuation Technology. Dual Attenuation Technology (DAT) is a unique 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.
