摘要：
A mass spectrometer includes a fragmentation cell having a plurality of ring or plate-like electrodes with apertures through which ions are transmitted. An axial DC gradient is preferably maintained along at least a portion of the length of the fragmentation cell in order to improve the transit time of ions through the device.
