High-Pressure Ion Mobility Spectrometry [PDF]
The effects of above-ambient pressure on ion mobility on resolving power, resolution, and ion current were investigated using a small, stand-alone ion mobility spectrometer (IMS). This work demonstrates the first example of ion mobility spectrometry at pressures above ambient.

Recent Progress in Protein Stereochemical Modifications Revealed by Ion Mobility-Mass Spectrometry [PDF]
Protein stereochemical modification (SCM) is a unique type of low-abundance post-translational modification associated with many human diseases. Because it does not change the molecular weight of proteins, traditional proteomics methods are generally not

Orthogonal extraction ion mobility spectrometry [PDF]
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.
