HYBRIDIZED ION PRE-SEPARATION FOR MASS SPECTROMETRY

原文（中国語）

A system includes a first pre-separation device configured to perform a first pre-separation of precursor ions according to mobilities of the precursor ions and a second pre-separation device positioned downstream of the first pre-separation device configured to perform a second pre-separation of precursor ions based on a mass-to-charge ratio (m/z) of the precursor ions. The system further includes a mass spectrometer positioned downstream of the second pre-separation device configured to acquire mass spectra for precursor ions emitted from the second pre-separation device. The second pre-separation device is synchronized with the mass spectrometer such that an m/z range of precursor ions emitted from the second pre-separation device corresponds to a precursor m/z isolation window of the mass spectrometer.
