Abstract: A mass spectrometer includes at least one ion guide having an inlet for receiving a plurality of ions from an upstream ion source and an outlet through which ions exit the ion guide, an ion routing device having an inlet for receiving at least a portion of the ions exiting the ion guide and at least two outlets, a first mass spectrometer positioned relative to the first outlet to receive ions exiting the ion routing device via the first outlet, and a second mass spectrometer positioned relative to the second outlet to receive ions exiting the ion routing device via the second outlet.

Abstract: In one aspect, a mass spectrometer is disclosed, which comprises an ion trap having a plurality of electrodes arranged in a multipole configuration so as to provide an inlet for receiving ions along a longitudinal axis into a space between the electrodes, where at least one of the plurality of electrodes comprises a passageway through which ions can be extracted radially from the ion trap. The electrodes are configured for application of one or more RF voltages thereto for providing radial confinement of the ions, and a DC voltage source configured to apply a dipolar DC voltage pulse across said at least one electrode and an opposed electrode for causing radial extraction of at least a portion of said ions from said ion trap through said passageway.

Abstract: Systems and methods described herein provide for the injection of ions into an ELIT at a variety of kinetic energies such that the ions turn around at various locations. In certain aspects, such systems and methods for operating an ELIT may reduce ion density at the turning points to reduce the impact of the space charge effect. Various aspects of the present teachings also provide for the design or optimization of the ELIT electrode spacing and/or injection potentials to reduce the impact of the space charge effect. In some related aspects, the ELIT may additionally provide time-focusing of the various ion groups at the detector as they oscillate along their respective path lengths.
