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 reduced before significant numbers of ion fragments are expelled from the ion trap, thereby decreasing the low-mass cutoff and allowing retention and subsequent measurement of lower-mass ion fragments.

In the field of mass spectrometry, a method and apparatus for fragmenting ions with a relatively high degree of resolution and efficiency. The technique includes trapping the ions in a linear ion trap, in which the background or neutral gas pressure is preferably on the order of 10<-5 >Torr. The trapped ions are resonantly excited for a relatively extended period of time, e.g., exceeding 50 ms, at relatively low excitation levels, e.g., less than 1 Volt(0-pk). The technique allows selective dissociation of ions with a high discrimination. High fragmentation efficiency may be achieved by superimposing a higher order multipole field onto the quadrupolar RF field used to trap the ions. The multipole field, preferably an octopole field, dampens the radial oscillatory motion of resonantly excited ions at the periphery of the trap. This reduces the probability that ions will eject radially from the trap thus increasing the probability of collision induced dissociation.
