Biological Mass Spectrometry, 1988
Positive and negative ion mobility spectra of dimenhydrinate are presented, and the calculated reduced mobility (K0) values for the most significant peaks are reported. Mass identification of the ionic species associated with the peaks in the ion mobility spectra was achieved by interfacing the ion mobility spectrometer to a mass spectrometer.

On an Anomaly in the Mobility of Gaseous Ions
Bell System Technical Journal, 1970Many mobility versus field curves for gaseous ions show a high mobility “bump” just above the ohmic range. The effect arises from the nature of the force between ions and molecules. It is effectively attractive for low speeds of encounter and repulsive for high speeds.

Ion mobility spectrometry and ion mobility-mass spectrometry in clinical chemistry
Advancements in clinical chemistry have major implications in terms of public health, prompting many clinicians to seek out chemical information to aid in diagnoses and treatments. While mass spectrometry (MS) and hyphenated-MS techniques such as LC-MS or tandem MS/MS have long been the analytical methods of choice for many clinical applications, theseKyle E, Lira +2 more

Ion mobility scanning ion chamber
IEE Proceedings A Science, Measurement and Technology, 1993An aspirated ion chamber measuring from natural atmospheric ion levels of 400 × 106 ions/m3 to 1.6 × 1012 ions/m3 over a mobility range of 2.77 to 0.004 × 10−4 m2/Vs which has been proven for field use, is described.

Publisher Summary Electron mobilities in dielectric liquids are strongly influenced by the molecular properties. If the molecules are spherelike, nonpolar, and do not capture the electrons, electrons tend to reside in a conduction band and have very high mobilities, up to ∼1 m 2 /V sec.

The Journal of Chemical Physics, 1972
Experimental data on the mobilities of the polyatomic ions SO2F−, SO2F2−, SF5−, SF6−, F−(SF6), and SO2F2–(SO2) in an He carrier gas were compared with the predictions of the mobility theories of Langevin and of Mason and Schamp. As a consequence of the low polarizability of He and the large size of the ions, these mobilities were found to be dominated ...

Ion Mobility and Tandem Ion Mobility Spectrometry for Top-Down Proteomics
The comprehensive characterization of human proteoforms remains a central bottleneck in elucidating molecular mechanisms underlying human disease. Top-Down Proteomics offers direct access to proteoforms but remains technically challenging, in large due to the difficulty of reliably interpreting fragment ions within highly complex tandem-mass spectra ...Fanny C.
