Ion mobility spectrometry (IMS), or used to be called as plasma chromatography, has been grown from atomic species for fundamental physical studies to nano-scale materials due to its unlimited detection size range. The development of electrospray ionization (ESI) has further expanded the application of IMS to the investigation of structural isomers and isobaric molecules of nonvolatile biomolecules in the gas phase combined with mass spectrometry (MS). ESI, which is a soft ionization method, transfers samples intact from the solution phase to the gas phase. Using this distinctive advantage of ESI, the shapes and sizes of various biomolecular ions from monomeric molecules to macro size complexes have been investigated. In this presentation, fundamental and applied studies of structural dynamics using IMS will be introduced. For example, correlation between van der Waals interaction and collision cross section values of molecules with various sizes will be introduced. Then, its unique applications to isolate and separate structural isomers will be further introduced.
