Abstract
A second gate in an Ion Mobility Spectrometer is used to select or block different time windows of the ion mobility spectrum. A second gate in the Ion Mobility Mass Spectrometer is used to modulate peak intensities in the IMS spectrum, allowing each peak in the IMS spectrum to be unambiguously matched with its set of fragment ions in a subsequent MS-MS mass spectrum.
