Low angle light scattering detector provides routine direct measurement of molecular weight for a wide range of synthetic polymers, natural polymers and proteins
Viscotek Europe's revolutionary low angle light scattering (Lals) detector provides routine direct measurement of molecular weight for a wide range of synthetic polymers, natural polymers and proteins.
Used with Viscotek's unique triple detector array (TDA), that also includes a differential refractometer and a patented four-capillary balanced bridge viscometer acting in concert, the new Lals detector allows direct determination of absolute molecular weight, size, density and conformation as well as providing structural information such as branching and aggregation.
Unlike multi-angle light scattering techniques that can only determine molecular weight by extrapolation, the Viscotek Lals measures molecular weight directly and thus is inherently more accurate.
Incorporating patented optical technology that will effectively operate at an angle of only 7deg the Lals detector represents a major breakthrough in light scattering technology.
