The ViscoStar ™ and microViscoStar ™ on-line differential viscometers measure 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 parameters.

Also useful for automation of Zimm plots, dn/dc analysis, reaction kinetics and polymer interaction analyses.
