Abstract:
An ion trap mass spectrometer includes an ion trap including a first electrode and a second electrode different from the first electrode, a first voltage controller that periodically switches a DV voltage among DC voltages having a plurality of values and apply the DV voltages to the first electrode, and a second voltage controller that applies a sine-wave voltage to the second electrode when ions captured in the ion trap are dissociated.
