Viscotek has announced new technical data that demonstrates how their unique Low Angle Light Scattering (LALS) detector achieves results not possible using traditional light scattering technologies. Operating at an angle of seven degrees, Low Angle Light Scattering is the only GPC detection method proven to provide absolute molecular weights without extrapolation or correction. Unlike other multi-angle light scattering techniques that can only determine molecular weight by extrapolation, the company`s detector directly measures molecular weight. The benefits of using it to calculate molecular weight is particularly evident when studying large synthetic polymers or biomolecules where traditional light scattering instruments give sizeable data fitting errors.
