Abstract:
An object is to measure both cations and anions with high duty cycle. In a mass spectrometer comprising an ion source (1), an ion guide part (31), and an ion trap (32), while ions are being mass-selectively ejected from the ion trap, ions having a polarity reverse to that of the ions trapped in the ion trap are introduced into the ion guide part.
