ABSTRACT:
A method of operating a quadrupole ion trap as a mass spectrometer, in which the ion mass to be detected is selected by adjusting the three dimensional quadrupole storage field to make the .beta..sub.z value of the selected mass equal to a fixed, predetermined .beta..sub.z value of a narrow range of frequencies excluded from a broadband supplemental RF electric field. The ions are detected to provide a signal corresponding to the amount of the selected ion mass.
