Abstract

PURPOSE:To improve measuring accuracy and efficiency by controlling supply to an ionization chamber of reaction gas according to magnitude of signal obtained through detection of vacuum level of the chamber. CONSTITUTION:An ionization chamber 1 is provided inside an ion source 2, then sample ions ionized in the chamber 1 are supplied in a mads analizer 3 so that the sample ions are mass-analyzed. Next, ions analyzed by the analyzer 3 are detected by a detector 4, mass scanning of the analyzer 3 is controlled, a control valve C is controlled so that the vacuum level may correspond to a set value, detection data of the detector 4 is stored and processed, and the data is displayed on a display 6. It is thus possible to control supply of reaction gas to the ionization chamber to an optimum level automatically.
