ABSTRACT:
A method for measuring the inherent viscosity of individual solute components in a multicomponent sample in solution with a solvent comprising for each component (1) measuring pressure differences for solvent and for solvent with solute component, as a function of time across two capillary tubes in fluid communication (2) measuring concentrations of component as a function of time, and (3) obtaining inherent viscosity by means of a described mathematical relationship.
