Abstract:
1. An ion trap-based system for chemical analysis, comprising: an ion trap array, said ion trap array including a plurality of ion traps arranged in a 2-dimensional array for initially confining ions, each of said ion traps comprising a central electrode having an aperture, a first and second insulator each having an aperture sandwiching said central electrode, and first and second end cap electrodes each having an aperture sandwiching said first and second insulator, structure for simultaneously directing a plurality of different species of said ions out from at least one of said ion traps, a spectrometer including a detector for receiving and identifying said ions based on arrival times, and a drift region or drift channel disposed between said end cap electrode and said detector, said drift region or drift channel having a length sufficient for resolving said arrival times of different species of said ions.
