摘要:
Depending on the RF driving voltage amplitude value and the frequency of each frequency component of wideband auxiliary AC voltages, the wideband auxiliary AC voltage comprising plural different frequency components is optimized so that undesired ions having mass-to-charge ratios within the required range will be resonantly ejected from the ion trap electrodes.
