Abstract
A mass spectrometer system having an ion trap and a downstream mass spectrometer is provided. A plurality of groups of ions are provided to the ion trap and a first mass-to-charge ratio is selected. The downstream mass spectrometer is configured to filter out one of (i) ions having a first unselected mass-to-charge ratio different from the first mass-to-charge ratio, and (ii) mass signals for ions having the first unselected mass-to-charge ratio different from the first mass-to-charge ratio. A first group of ions is ejected of the first mass-to-charge ratio from the ion trap to the downstream mass spectrometer.
