１引言用毛细管胶束电动色谱（ＭＥＫＣ）对ＰＴＣ氨基酸分离条件进行研究，建立ＭＥＫＣ分离１７种ＰＴＣ氨基酸的方法。结果表明，在２０ｍｉｎ内１７种ＰＴＣ氨基酸得到比较满意的分离，方法回收率为９５％～１０３％，在６０μｍｏｌ／Ｌ浓度范围内均呈线性，相关系数ｒ＞
1 Introduction The separation of PTC amino acids by capillary micellar electrokinetic chromatography (MEKC) was studied to establish a method for the separation of 17 kinds of PTC amino acids by MEKC. The results showed that 17 kinds of PTC amino acids were satisfactorily separated in 20 min, the recoveries were between 95% and 103%, linear in the concentration range of 60 μmol / L, the correlation coefficient r>
