Abstract
A dual-mode ion detector for a mass and/or ion mobility spectrometer comprising a first conversion electrode () that is maintained, in use, at a negative potential and arranged for converting incident positive ions () into secondary electrons (), and a second conversion electrode () that is maintained, in use, at a positive potential and arranged for converting incident negative ions () into secondary positive ions () and/or secondary electrons (). The detector also comprises an electron detecting surface () and an entrance electrode () for drawing ions into the ion detector. The ion detector is switchable between a first mode for detecting positive ions and a second mode for detecting negative ions.
