This review surveys the recent progress in the adsorbed stationary phases for capillary electrochromatography (CEC). Adsorption‐based methods for preparation of stationary phase are novel approaches in CEC, which allow rapid and facile preparing stationary phases with desirable selectivity onto an open‐tubular fused‐silica capillary, a bare‐silica or ion‐exchange packed column or a monolithic silica or polymer column. A variety of adsorbing agents have been developed as adsorbed stationary phases, including ionic long‐chain surfactant, protein, peptide, amino acid, charged cyclodextrin (CD), basic compound, aliphatic ionene, and ion‐exchange latex particle. The adsorbed stationary phases have been applied to separation of neutral, basic and acidic organic compounds, inorganic anions and enantiomers. They have also been applied to on‐line sample concentration, fast separation and study of the competitive binding of enantiomers with protein.
