Abstract

A plug electroosmotic velocity profile is generally assumed to be characteristic of capillary electrochromatography. However, this ideal plug flow may be illusive in some experiments with packed-capillary columns due to overlap of electrical double layers in flow channels. We report here a theoretical analysis of the double-layer overlap effects in packed… (More)
