Abstract

A mass spectrometer is provided having a plurality of analyzers and including at least one magnetic sector analyzer and, typically, an orthogonal-acceleration time-of-flight mass analyzer. Bypass means are provided so that by switching of the direction of the ion beam, the magnetic sector analyzer may be bypassed and the time-of-flight analyzer used either to analyse the beam of ions from the source or daughter ions produced by fragmentation of that beam.
