    摘要: The present invention maintains a stable emission amount from an emitter. In an embodiment of the present invention, a solid sample or a liquid sample is heated to gasify an object to be measured contained in the solid sample or the liquid sample, thereby forming a neutral gaseous molecule, and a metal ion emitted from an emitter having an oxidized surface is attached to the neutral gaseous molecule to ionize the neutral gaseous molecule, which is subjected to mass spectrometry. The solid sample or the liquid sample is a sample that emits a reducing gas by heating. The heating for gasifying the object to be measured is performed at a temperature lower than the vaporization temperature of the solid sample or the liquid sample and not less than the vaporization temperature of the object to be measured, and an oxidizing gas is provided to the emitter.

    摘要: An ion attachment mass spectrometer includes an attached ion generation unit which generates attached ions by attaching positively charged metal ions to the molecules of a measurement target substance, and a mass spectrometry unit which performs mass spectrometry of the attached ions. The mass spectrometry unit includes a mass separation chamber to select attached ions having a specific mass number from the attached ions, an ionization chamber to dissociate the attached ions having the specific mass number, and a mass analysis chamber to analyze the dissociated ions.
