Electroextraction (EE) is a sample enrichment technique that focuses charged analytes from a large volume of one phase into a small volume of aqueous phase through the application of an electric current. The technique was originally developed as a separation technique for chemical engineering, but has since been coupled to capillary electrophoresis and liquid chromatography–mass spectrometry as a means of improving limits of detection, analysis time, and selectivity. The use of EE-CE has made capillary electrophoresis more applicable to use in the pharmaceutical industry.

In this article, electroextraction describes the extraction of charged particles through a liquid phase barrier. The term can be used to describe electrowinning, which is the extraction of metals from their compounds via electrochemical processes. Electroextraction also describes a process of permeating bioproducts from a cell membrane using an electric field.
