Differential mobility spectrometry (DMS) is capable of separating molecules based on their size and shape. When coupled to mass spectrometry (MS), DMS reduces chemical background and enhances signal-to-noise (S/N) ratio. Flow injection analysis (FIA) is a technique used to introduce samples into the source of the DMS-MS platform. Here we describe the application of FIA-DMS-MS/MS for the analysis of urinary acylcarnitine species. More than 20 acylcarnitine species can be detected and quantified during a single FIA-DMS-MS/MS acquisition.
