Abstract
A mass spectrometer includes a radio frequency ion trap and a controller. The controller is configured to cause an ion population to be injected into the radio frequency ion trap and supply an isolation waveform to the radio frequency ion trap. The isolation waveform has at least one notch at a target mass-to-charge ratio and a frequency profile determined to eject unwanted ions at a plurality of frequencies in a substantially similar amount of time.
