Abstract

An ion guide includes a series of electrodes disposed between first and second ends of the ion guide. A controller is configured to determine that the ion guide is to operate in a mass-to-charge ratio (m/z) separation mode to separate ions primarily based on m/z of the ions or an ion mobility separation mode to separate ions primarily based on a mobility of the ions. The controller is further configured to set an attribute of radio-frequency (RF) voltage waveforms that are to be applied to the series of electrodes and to cause the RF voltage waveforms to be applied while the ion guide operates in the select mode. The RF voltage waveforms cause spatial separation of the ions within the ion guide and generate a plurality of moving pseudopotential wells that exert forces that urge the ions to migrate towards the second end of the ion guide.
