The ViscoStar® III on-line differential viscometer measures the intrinsic viscosity of polymers downstream of SEC. Differential viscometry is best combined with MALS and RI for analysis of polymer conformation and Mark-Houwink-Sakurada parameters.

On its own, the ViscoStar can determination hydrodynamic radius, or may be utilized with the Universal Calibration technique to assess polymer molar mass / molecular weight over a wide range.
