Targeted glucocorticoid analysis using ion mobility-mass spectrometry (IM-MS)

Journal of Mass Spectrometry and Advances in the Clinical Lab, 2022
Ion mobility-mass spectrometry (IM-MS) is an emerging technique in the -omics fields that has broad potential applicability to the clinical lab. As a rapid, gas-phase structure-based separation technique, IM-MS offers promise in isomer separations and can be easily combined with existing LC-MS methods (i.e., LC-IM-MS).

Predicting Optimal Resolving Power for Ambient Pressure Ion Mobility Spectrometry (IMS)

Analytical Chemistry, 2008
Although diffusion theory predicts that IMS resolving power increases with the square root of the voltage applied across the drift tube, in practice there exists an optimum voltage above which resolving power decreases.
