Micellar electrokinetic chromatography-chemiluminescent detection of biogenic amines using N-(4-aminobutyl)-N-ethylisoluminol as derivatization reagent and trivalent copper chelate as chemiluminescence enhancer

► DPC was found to be an excellent enhancer for luminol-H2O2 CL system. ► Derivatization of biogenic amines was accomplished with a TEA-catalyzed method. ► A MEKC-CL method was established for highly sensitive detection of amino acids.
