摘要: 以3-对羟基苯甲酰喹啉-2-甲醛(CBQCA)为检测痕量氨基酸的柱前衍生试剂,利用高效液相色谱-激光诱导荧光-增强型电荷耦合器件检测器(HPLC-LIF-ICCD)系统,考察了氨基酸衍生和HPLC分离过程中多种因素的影响,建立了HPLC-LIF-ICCD分离检测痕量氨基酸的新方法,并应用于鼠脑微透析液的氨基酸检测.当信噪比为3时,对甘氨酸的质量检出限为5fmol.

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.

Key words: High performance liquid chromatography, Laser induced fluorescence, Intensified charge coupled device, Separation, Microdialysis
