Isolating ions in quadrupole ion traps for mass spectrometry |
摘要 |
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). The ejection waveforms have frequency components in a first and a second dimension, and, are applied across electrodes aligned along a first and a second dimension. Thus the mass-to-charge ratio isolation window is controlled and has an improved resolution without increasing the number of frequency components.
