Designing advanced stationary phases to improve separation efficiency is essential in capillary electrochromatography. Due their outstanding performance, covalent organic frameworks have recently demonstrated considerable promise the field of science. Herein, an open-tubular electrochromatography method was reported using porous imine-based framework with sufficiently available interaction sites as phase. The coated easily prepared via situ growth at room temperature, and its performance evaluated, indicating high for three types analytes, including herbicides, polybrominated dibenzofurans, bisphenols. Moreover, showed good reproducibility stability, intraday (n = 3), interday column-to-column 3) relative standard deviations retention time peak areas less than 5%. remained unchanged even after 200 runs maximum theoretical plates reached up 85 595 N/m 4,4'-ethylidenebisphenol. It predicted that phase would be a strong contender chromatographic efficiency.

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