Abstract
A mass spectrometer includes a flight control device for allowing ions from an ion source to repeatedly fly along an orbit in a flight space for predetermined times; a detecting device for detecting the ions after the ions repeatedly fly along the orbit for the predetermined times; and a data processing device for starting collection of ion strength data detected by the detecting device. The ion strength data is obtained during the flight of the ions along the orbit, or when the ions are headed toward the detecting device after departing from the orbit, or when one of the above situations is estimated.
