Abstract
PURPOSE:To extend the life of a detector and a secondary electron multiplier tube by controlling the scanning voltage applied to a electrode member so that an element with the specific mass contained in a sample does not pass the electrode member. CONSTITUTION:The output of a computer 21 is fed to a controller 22, and the scanning voltage applied to an electrode member 17 from e voltage power source 23 is controlled by the controller 22. The controller 22 also controls the scanning voltage applied to the electrode member 17 from the voltage power source 23 so as to scatter, e.g., water-related ions with masses 16-19 and argon- related ions with masses 40, 41 for scanning. Argon-related ions and water- related ions forming large-background ions do not reach a secondary electron multiplier tube 20. A large current is thereby prevented from flowing in a detec tor or the secondary electron multiplier tube 20, and the life of the detector or the secondary electron multiplier tube can be extended.
