ABSTRACT:
A mass spectrometer includes an ion detector positioned upstream of a quadrupole mass filter/analyser. Ions are passed through the quadrupole mass filter/analyser, stored in an ion trap and then passed back through the same mass filter/analyser before being detected by the upstream ion detector. With this arrangement, MS/MS experiments can be performed using an apparatus having only a single mass filter/analyser.
