自1820年Braconnot首次从明胶蛋白水解液中分离出甘氨酸以来,人们对氨基酸的分析方法不断探索,几乎使用了所有形式的层析与电泳技术。目前已有氨基酸自动分析仪及高效液相等先进手段,可以精确地进行氨基酸分析。然而这类大型仪器不但价格昂贵, Since the first separation of glycine from the gelatin hydrolysate by Braconnot in 1820, the method of analysis of amino acids has been continuously explored. Almost all types of chromatography and electrophoresis techniques have been used. At present, there are advanced methods such as automatic amino acid analyzers and high-performance liquids that allow accurate amino acid analysis. However, such large-scale instruments are not only expensive,
