Abstract
A charge detection mass spectrometer may include an electrostatic linear ion trap (ELIT) or an orbitrap, an ion source to supply ions thereto, at least one amplifier operatively coupled to the ELIT or orbitrap, a processor coupled to ELIT or orbitrap and to the amplifier(s), and processor programmed to control the ELIT or orbitrap as part of a trapping event to attempt to trap therein a single ion supplied by the ion source, to record ion measurement information based on output signals produced by the amplifier(s) over a duration of the trapping event, to determine, based on the measurement information, whether the control of the ELIT or orbitrap resulted in trapping of a single ion, no ion or multiple ions, and to compute an ion mass or mass-to-charge ratio from the measurement information only if a single ion was trapped during the trapping event.
