ABSTRACT:
An ionising particle analyser comprises a source of ionising particles, a charged particle detector, and an ionisable gas located between the source and the detector. The analyser further comprises a charged particle impeding device located between the source and the detector. The charged particle impeding device is arranged to be maintained in a first configuration at a potential to impede the passage of charged particles and pass uncharged particles.
