Abstract

In this work we report a method to reduce Taylor dispersion for chromatographic applications by introducing vortices, lateral to the pressure driven flow. We show a fundamental improvement of a reversed-phase chromatographic separation of coumarin 440 and coumarin 480 by inducing vortices in lateral direction, increasing the resolution from 1.3 to 2.05. Since coumarins are relatively fast diffusing molecules, slowly diffusing molecules such as large proteins and other large biomolecules would benefit even more from the displayed technique.
