Methods and systems for separating, detecting, and/or quantifying sample enantiomers using differential mobility spectrometry (DMS) are provided herein. In accordance with various aspects of the applicant's teachings, the methods and systems can provide for the separation of racemic or non-racemic mixtures of sample enantiomers that may be difficult to separate with conventional techniques, such as mass spectrometry (MS), by reacting the sample enantiomers with an enantiomerically-pure compound to form diastereomers separable by DMS.
本文提供了使用差示迁移率光谱法(
DMS)分离、检测和/或量化样品对映体的方法和系统。根据申请人教导的各个方面,这些方法和系统可以通过使样品对映体与对映体纯化合物反应形成可通过
DMS 分离的非对映体,从而分离外消旋或非外消旋样品对映体混合物,这些混合物可能难以用传统技术(如质谱法)分离。
