Abstract (en)
[origin: EP1505634A2] A mass spectrometer is disclosed comprising a fragmentation cell 1 comprised of a plurality of ring or plate-like electrodes having 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 1 in order to improve the transit time of ions through the device.
