Differential-Mobility Spectrometry of 1‑Deoxysphingosine Isomers: New Insights into the Gas Phase Structures of Ionized Lipids

Separation and structural identification of lipids remain a major challenge for contemporary lipidomics. Regioisomeric lipids differing only in position(s) of unsaturation are often not differentiated by conventional liquid chromatography–mass spectrometry approaches leading to the incomplete, or so...
