Viscometric Detection in Size-Exclusion Chromatography: Principles and Select Applications

Size-exclusion chromatography (SEC) has benefitted from commercially available on-line viscometers for 30 years now. Initial (and continued) interest was mostly in applying the universal calibration concept to obtain molar mass averages and distributions of macromolecules for which no appropriate calibration standards existed, and in obtaining long-chain branching information such as branching number and frequency. During the last three decades,...
