Rapid and efficient fragmentation of ions in an ion trap for MS/MS analysis is achieved by a pulsed fragmentation technique. Ions of interest are placed at an elevated value of Q and subjected to a relatively high amplitude, short-duration resonance excitation pulse to cause the ions to undergo collision-induced fragmentation. The Q value of the ions of interest is then rapidly reduced, thereby decreasing the low-mass cutoff and allowing retention and subsequent analysis of low-mass ion fragments.

A mass spectrometer includes an ion mobility spectrometer or separator arranged upstream of a collision or fragmentation cell. Ions are separated according to their ion mobility within the ion mobility spectrometer or separator. The kinetic energy of the ions exiting the ion mobility spectrometer or separator is increased substantially linearly with time in order to optimize the fragmentation energy of ions as they enter the collision or fragmentation cell. During the time that the potential of the ion mobility spectrometer or separator is being varied, the potential of ion-optical components upstream of the ion mobility spectrometer or separator such as an ion source, ion guide, quadrupole mass filter, optional second collision or fragmentation cell and an ion trapping device are kept constant.
