Recent Advances in the Construction and Applications of Monolithic and Open‐tubular Capillary Electrochromatography (2022–2024)

ABSTRACT Capillary electrochromatography (CEC) has attracted significant attention and gained considerable recognition in the field of separation science owing to its excellent separation efficiency. While numerous reviews on CEC have been published in recent years, a comprehensive and systematic summary of the typical synthesis strategies for electrochromatographic stationary phases and their state‐of‐the‐art applications in CEC remains lacking. This review highlights recent advances (over the past 3 years) and representative applications (including chiral separation, microextraction‐coupled analysis, metabolomics, enzyme analysis, and food analysis) of monolithic and open‐tubular stationary phases in CEC. The advantages and limitations of each methodology are critically analyzed to present a balanced evaluation. Additionally, this work outlines future prospects regarding the development trends in electrochromatographic stationary phase preparation methods and the evolving applications of CEC.
