Fundamentals of ion mobility spectrometry [PDF]
Current Opinion in Chemical Biology, 2018 Fundamental questions in ion mobility spectrometry have practical implications for analytical applications in general, and omics in particular, in three respects. (1) Understanding how ion mobility and collision cross section values depend on the collision gas, on the electric field and on temperature is crucial to ascertain their transferability ...

Orthogonal extraction ion mobility spectrometry [PDF]
Journal of the American Society for Mass Spectrometry, 2006 Ion Mobility Spectrometry is a powerful tool for the study of molecular conformations, separation of mass isomers, and analysis of complex mixtures and suppression of chemical background. The factors that limit the capabilities of the technique include its relatively low resolving power and duty cycle.

Ion mobility mass spectrometry of saponin ions [PDF]
Rapid Communications in Mass Spectrometry, 2018 Rationale Saponins are natural compounds presenting a high structural diversity whose structural characterization remains extremely challenging. Ideally, saponin structures are best established using nuclear magnetic resonance experiments conducted on isolated molecules.

Effect of Humidity on the Mobilities of Small Ions in Ion Mobility Spectrometry
Analytical Chemistry, 2023 Ions in the ion mobility spectrometry (IMS) are mostly hydrated. A single peak in the drift time spectrum is usually generated by a mixture of ions differing in the number of attached water molecules. Under real IMS detector operating conditions, ions change their composition during movement in the drift region due to the changes in the number of water
