Abstract: A High performance liquid chromatography-laser induced fluorescence-intensified charge coupled device(HPLC-LIF-ICCD) system was used for the analysis of amino acid. Using 3-(4-carboxybenzoyl)-2-quinoline-carboxyaldehyde(CBQCA) as a derivatizing agent, several factors influencing the derivatization and separation of amino acid were investigated in detail. The mass detection limit of glycine was 5×10-15 mol. The method was applied to the detection of amino acids in rat brain microdialysates.
