Viscotek have announced new technical data that demonstrates howtheir unique Low Angle Light Scattering (LALS) detector achievesresults not possible using traditional light scatteringtechnologies.
Operating at an angle of only 7 degrees - Low Angle LightScattering is the only GPC detection method proven to provideabsolute molecular weights without extrapolation or correction.Unlike other multi-angle light scattering techniques that can onlydetermine molecular weight by extrapolation, the Viscotek LALSdirectly measures molecular weight. The benefits of using LALSdetection to calculate molecular weight is particularly evidentwhen studying large synthetic polymers or biomolecules wheretraditional light scattering instruments give sizeable data fittingerrors.
As part of Viscotek's unique Triple Detector Array (TDA), theinnovative LALS detector represents a significant enhancement tothe most comprehensive and flexible molecular characterisation toolon the market. The Viscotek TDA with LALS allows directdetermination of absolute molecular weight, molecular size, densityand conformation, and provides structural information on branchingand aggregation.
