Abstract
A charge detection mass spectrometer may include an ion source to generate ions, a mass spectrometer to separate the generated ions as a function of ion mass-to-charge ratio to produce beam of separated ions, an electrostatic linear ion trap (ELIT) including a charge detection cylinder disposed between a pair of coaxially aligned ion mirrors, and means for controlling a trajectory of the beam of separated ions entering the ELIT to cause the ions subsequently trapped in the ELIT to oscillate therein with different planar ion oscillation trajectories angularly offset from one another about the longitudinal axis with each extending along and crossing the longitudinal axis in each of the ion mirrors or with different cylindrical ion oscillation trajectories radially offset from one another about the longitudinal axis to form nested cylindrical trajectories each extending along the longitudinal axis.
