A new 8-page technical brochure is available from Viscotek - that describes its recently launched second generation Model 802 Dynamic Light Scattering (DLS) instrument.
For those new to DLS the new brochure provides background to the technique and applications of dynamic light scattering. Further well illustrated text provides an in-depth review of the performance advantages born out of Viscotek's exclusive single mode fibre technology as well as introducing a range of exciting new technical innovations pioneered in the new generation Model 802 DLS.
Designed for laboratories that need a complete understanding of how their protein, biopolymer or nanoparticulate material behaves in solution the new ergonomically designed Model 802 DLS sets a new standard for superior sensitivity, resolution, accuracy and sampling versatility compared to any other light scattering instrument currently available.
Traditionally laboratories faced with analysing higher concentration samples, such as emulsion or nanoparticles, 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. In combination with OmniSIZE 3.0 software the new generation Model 802 DLS with DAT is able to automatically adjust the instrument to its optimum setting sample by sample. From 100% transmission for the maximum sensitivity right down to 0.0001% transmission for concentrated samples - a dynamic range of 106.
Further innovations introduced on the new Model 802 DLS include a 544-channel correlator that provides, as standard, industry leading resolution and distribution accuracy. In addition to operating up to 90°C the new instrument now incorporates digital sensors that provide automatic environmental control as well as real-time humidity and dew point information.
Founded in 1985, Viscotek is the global leader in Gel Permeation Chromatography (GPC) / Size Exclusion Chromatography (SEC) detectors, software and systems for the characterisation of natural and synthetic polymers, copolymers, proteins, protein conjugates and nanoparticulate materials. Viscotek's innovative products and technologies are backed in Europe, North America and Asia by superior technical service and analytical support.
