A vanillin imprinted capillary monolithic column was synthesized by in situ polymerization reaction using ethylene‐glycol dimethacrylate as cross‐linking monomer and methacrylic acid as functional monomer. Under the optimum conditions of capillary electrochromatography, this molecularly imprinted polymer (MIP)‐based column showed high selectivity and could recognize not only template molecule vanillin but also positional isomer o ‐vanillin from their structural analogues.
