Abstract: An ion resonance excitation operation method and device by applying a quadrupolar electric field combined with a dipolar electric field. The method includes applying a main RF to any pair of plates of the ion trap mass analyzer, and applying a quadrupolar excitation signal to any pair of plates, and applying a reverse phase dipolar excitation signal to any pair of plates. Also provided is an ion resonance excitation operation method and device by using a quadrupolar electric field combined with a dipolar electric field, which includes applying a positive main RF to a pair of electrode rods of the quadrupole, and applying a negative main RF to the other pair of electrode rods; applying a quadrupolar excitation signal to any pair of electrode rods, applying a reverse phase dipolar excitation signal to any pair of electrode rods.
