Abstract

Basic conditions for the on-line neutral sample concentration by reversed electrode polarity stacking mode for micellar electrokinetic chromatography are developed theoretically and experimentally verified. Stacking is mainly dependent on analyte retention factors and nature of the pseudostationary phases. More than an order of magnitude improvement in concentration detection limit is achieved for resorcinol using high molecular mass surfactants.
