      Coupling ion mobility (IM) with MS offers a potential solution for resolving structural isomers. Ion mobility separates ions according to size and shape because they interact differently with the neutral drift-gas molecules. However, the majority of routine IM-MS measurements rely on drift-gases with low polarizability such as He and N2. In the Special Feature Lalli et al. investigate polarizable molecules as drift-gas to determine if the dipolar ion-neutral interactions enhance ion mobility separations of shape-similar analytes. Their results suggest that the polarizability of the drift-gas and the distribution of charge on the ion influence the degree of IM separation.
