Low Angle Light Scattering Detector

The LALS measures absolute molecular weights without extrapolation or correctionViscotek proudly announces a major breakthrough in light scattering technology for determination of absolute molecular weight - a new Low Angle Light Scattering (LALS) detector that surpasses traditional technologies and will operate at an angle of 7 degrees.

Low Angle Light Scattering is the only GPC detection method that provides absolute molecular weights without extrapolation or correction. Unlike multi-angle light scattering techniques that can only determine absolute molecular weight by extrapolation, the Viscotek LALS directly measures absolute molecular weight for a large range of synthetic polymers, natural polymers and proteins.

As part of Viscotek's unique Triple Detector Array (TDA), the new LALS represents a significant enLALS can measure the absolute molecular weight of synthetic polymers, natural polymers and proteinshancement to the most comprehensive and flexible molecular characterization tool on the market. The Viscotek TDA with LALS allows direct determination of absolute molecular weight, molecular size, density and conformation, and provides structural information on branching and aggregation.
