An electrospray ionization mass spectrometric method for the simultaneous analysis of the enantiomeric excess of free amino acids, without chromatographic separation, was demonstrated using a quasi-racemic mixture of deuterium-labelled and unlabelled chiral copper(ii) complexes. This convenient method enables the simultaneous high-sensitivity determination of the enantiomeric excess of 12 amino acids.
使用氘标记和未标记的手性铜（II）配合物的准外消旋混合物，展示了一种无需色谱分离即可同时分析游离氨基酸对映体过量的电喷雾电离质谱方法。这种便捷的方法能够同时高灵敏度地测定12种氨基酸的对映体过量。
