Linear ion trap mass selectivity with impulse power supply and sinusoidal dipolar excitation

摘要

RATIONALE: An ion trap mass analyzer can be operated by either a sinusoidal waveform power supply or an impulse waveform power supply. The optimal conditions for the performance of ion trap which is driven by an impulse waveform power supply with sinusoidal dipolar voltage were investigated theoretically, and further verified by experiments.
