Abstract
A mass spectrometer is disclosed comprising an orthogonal acceleration Time of Flight mass analyser. A pulse or packet of ions is released either from an ion trap or alternatively from a travelling wave ion guide arranged upstream of an orthogonal acceleration electrode which forms part of the Time of Flight mass analyser. Ions in the pulse or packet or ions which is released become temporally dispersed and the orthogonal acceleration electrode is energized multiple times prior the release of a subsequent pulse or packet of ions.
