ABSTRACT:
Ions in a predefined narrow mass to charge ratio range are isolated in an ion trap by adjusting the field and using ejection frequency waveform(s). Thus the mass-to-charge ratio isolation window is controlled and has an improved resolution without increasing the number of frequency components.
