Abstract

The present invention relates generally to components of scientific analytical equipment. More particularly, but not exclusively, the invention relates to electron multipliers and modifications thereto for extending the operational lifetime or otherwise improving performance by way of improved construction. The invention may be embodied in the form of a detector comprising one or more electron emissive surfaces, the detector comprising one or more detector elements configured to define on one side an environment internal the detector and on the other side an environment external the detector,wherein the one or more detector elements are configured to inhibit or prevent flow of a gas from the environment external the detector to the environment internal the detector. Such detectors may beused in a mass spectrometry instrument.

Description

technical field [0001] The present invention generally relates to components of scientific analysis equipment. More particularly, but not exclusively, the present invention relates to electron multipliers and modifications thereof for extending operational life or otherwise improving performance through improved construction. Background technique [0002] In a mass spectrometer, analytes are ionized to form a series of charged particles (ions). The resulting ions are then separated according to their mass-to-charge ratios, typically by acceleration and exposure to electric or magnetic fields. The separated signal ions impinge on the surface of the ion detector to generate one or more secondary electrons. Results are displayed as spectra of the relative abundance of the detected ions as a function of mass-to-charge ratio. [0003] In other applications, the particles to be detected may not be ions, but may be neutral atoms, neutral molecules or electrons. In any case, the...
