摘要
Methods, apparatus and systems for acquiring spectrometric data from analyte ions implement a combination of drift-type ion mobility (IM) separation and time-of-flight mass spectrometry (TOF MS). Both separation techniques are carried out in tandem while applying mass filtering with a wide window of ion isolation. One mode of operation entails utilizing a mass filter to limit ion packets to ions in a selected m/z range that remains constant over the entire course of data acquisition. Another mode entails utilizing the mass filter to limit ion packets to an m/z range that varies over the course of data acquisition.
