Evaluation and Application of a Commercial Single Capillary Viscometer System for The Characterization of Molecular Weight Distribution and Polymer Chain Branching

Abstract: The objective of this paper is to critically evaluate the performance of the newly introduced Millipore Waters GPCviscometer system. In particular, the capabilities of the data analysis methodology are evaluated and limitations are identified. methodology and to make it more user friendly are suggested.

“…Viscosity detectors measure the pressure drop in a capillary, or a set of capillaries, to estimate specific viscosity of the solution. Single capillary viscometers [54] are usually strongly effected by any fluctuations in the flow of mobile phase and are typically used with a syringe pump to alleviate this problem. Alternatively, pulsation effects can be eliminated when two capillaries are used in series.…”
