As　an　emerging　microseparation　technology,capillary　electrochromatography　(CEC)　has　drawn　more　and　more　attention　in　recent　years,　since　it　combines　both　the　merits　of　high　efficiency　of　capillary　electrophoresis　and　robust　selectivity　of　high　performance　liquid　chromatography.　The　basic　principle,　the　column　techniques　and　commonly　used　detectors　of　CEC　are　introduced　simply.　Especially,　the　technique　of　capillary　electrochromatography　coupled　with　laser-induced　fluorescence,　including　its　application　in　the　fields　of　biochemical　analysis,　clinical　medicine　and　environmental　monitoring　is　summarized.
