1. An ion storage mass spectrometer, comprising:
an ion source for providing ions;
a first ion separator for separating the ions into a plurality of ion groups based on ion mobility or mass, each different ion group comprising ions within a different known mass or mobility window;
a second ion separator for further separating each of said plurality of ion groups into a plurality of ion sub-groups based on mass-to-charge ratio (m/z), each of the different ion sub-groups of each ion group comprising ions within a different known mass sub-window of the respective ion group mass or mobility window;
one or more mass analyzers for analyzing the ions of each ion sub-group; and
an ion storage array comprising a plurality of independently operable ion storage cells, the ion storage array being one of:
i) disposed between the first ion separator and the second ion separator for receiving the plurality of ion groups from the first ion separator, for storing each received ion group within a different predetermined ion storage cell, and for selectively releasing said ion groups for introduction into the second ion separator; or
ii) disposed between the second ion separator and the one or more mass analyzers for receiving the plurality of ion sub-groups from the second ion separator, for storing each received ion sub-group within a different predetermined ion storage cell, and for selectively releasing each of said ion sub-groups for introduction into the one or more mass analyzers.
