Ion mobility spectrometry-mass spectrometry (IMS-MS) of small molecules: separating and assigning structures to ions [PDF]

open access: yesMass Spectrometry Reviews, 2013
The phenomenon of ion mobility (IM), the movement/transport of charged particles under the influence of an electric field, was first observed in the early 20th Century and harnessed later in ion mobility spectrometry (IMS). There have been rapid advances
