Gas Phase Stability of Protein Ions in a Cyclic Ion Mobility Spectrometry Traveling Wave Device [PDF]
Analytical Chemistry, 2018 Ion mobility mass spectrometry (IM-MS) allows separation of native protein ions into “conformational families”. Increasing the IM resolving power should allow finer structural information to be obtained, and can be achieved by increasing the length of the IM separator.

Native Ion Mobility Mass Spectrometry: When Gas-Phase Ion Structures Depend on the Electrospray Charging Process [PDF]
Journal of the American Society for Mass Spectrometry, 2018 Ion mobility spectrometry (IMS) has become popular to characterize biomolecule folding. Numerous studies have shown that proteins that are folded in solution remain folded in the gas phase, whereas proteins that are unfolded in solution adopt more extended conformations in the gas phase. Here, we discuss how general this tenet is.

Gas-Phase Chiral Separations by Ion Mobility Spectrometry [PDF]
Analytical Chemistry, 2006 This article introduces the concept of chiral ion mobility spectrometry (CIMS) and presents examples demonstrating the gas-phase separation of enantiomers of a wide range of racemates including pharmaceuticals, amino acids, and carbohydrates. CIMS is similar to traditional ion mobility spectrometry, where gas-phase ions, when subjected to a potential ...

Glycan analysis by ion mobility-mass spectrometry and gas-phase spectroscopy [PDF]
Current Opinion in Chemical Biology, 2018 Due to the existence of numerous isomers, the in-depth analysis of glycans represents a major challenge. Currently, the majority of glycans are analysed using mass spectrometry (MS)-based techniques, which can provide information on regioisomers but usually fail to differentiate stereoisomers.
