Electrokinetic removal of charged species from small sample volumes.

Abstract

Cationic or anionic molecules can be selectively injected from an aqueous mixture of charged and neutral species into a capillary by electrophoresis. Under stacking conditions, this selective field enhanced sample injection was studied here as a potential sample preparation technique for the clean-up or purification of microliter samples. As a simple… (More)
