## Abstract In aqueous capillary electrophoresis the electroosmotic flow (EOF) can be strongly suppressed or eliminated by coating the capillary surface silanols either by buffer additive adsorption or chemical modification. Hydrophilic coatings, __e.g.,__ polyvinyl alcohol (PVA) proved to be most
One can increase the residence time of analytes in a capillary electrophoresis experiment by reducing the electroosmotic flow. Such measures increase separation efficiency and resolution. It is possible to accomplish this by hydrostatic backflow but dispersion induced by the parabolic flow profile c
