Counter-flow gradient electrofocusing methods are methods whereby a combination of electrophoresis and a bulk solution counter-flow is used to accumulate or focus analytes at stationary points along a separation column. This review first describes the various forms of counter-flow gradient electrofocusing that have been demonstrated in the literature, and then compares figures of merit for counter-flow focusing methods and conventional CE methods.
