Abstract

A mass spectrometer includes an ion trap, which has an interior for storing ions, a signal generator, which is connected to an electrode of the ion trap, which delimits the interior, for coupling in a voltage signal, in particular a radiofrequency voltage signal, and an ionization device for ionizing a gas to be ionized and supplied to the interior. The ionization device is connected to the signal generator in order to use the voltage signal (URF, UStim1, Ustim2) of the signal generator, which is coupled into the electrode, for generating ions.
