Capillary zone electrophoresis and polymer dynamics

Abstract

Capillary electrophoresis with a polymer solution support medium is a well-established powerful analytical tool. This paper discusses a possible alternative application of capillary electrophoresis, namely a path for studying the dynamics of polymer solutions. The key to the approach is an inversion of perspective. Instead of treating the migrating species as the object of experimental importance and the support medium as being of importance only because it facilitates separations, one treats the polymer solution as being of experimental importance, and the choice of migrating species as being of interest only because different species may probe different aspects of polymer dynamics.

Interpretation of quasielastic scattering spectra of probe species in complex fluids

“…The emphasis of this work is on separating charged species. However, separations using, e.g., neutral polymer solutions as support media, equally give information on the dynamics of the support medium [4,16]. A substantial literature exists on ultracentrifugal sedimentation in complex fluids [17,18].…”
