    摘要： A mass spectrometric apparatus capable of generating and detecting positive and negative ions stably at the same time. The apparatus preferably comprises: an opening through which a sample gas is introduced; an ion source to generate ions of the sample gas; and a mass spectrometer to analyze the mass of the generated ions. The ion source utilized with the mass spectrometric device comprises: a first needle electrode on which a voltage is applied in order to generate positive ions of the sample gas introduced through the opening; a first counter electrode having a first opening through which the sample gas and the positive ions pass; a second counter electrode disposed opposite the first counter electrode having a second opening through which the sample gas and the positive ions pass; a second needle electrode on which voltage is applied in order to generate negative ions of the sample gas; and a vent through which the sample gas is ejected. Generated ions are then introduced into a vacuum region via an aperture and subjected to mass analysis.

    摘要： An apparatus for detecting chemical substances which is high in sensitivity and selectivity is provided. An organic acid or an organic acid salt is used to generate an organic acid gas from an organic acid gas generator to be mixed with a sample gas for introduction into an ion source for ionization, thereby obtaining a mass spectrum by a mass analysis region. A data processor determines the detection or non-detection of a specific m/z of an organic acid adduct ion obtained by adding a molecule generated from the organic acid to a molecule with specific m/z generated from a target chemical substance to be detected based on the obtained mass spectrum. When there is an ion peak with the m/z of the organic acid adduct ion, the presence of the target chemical substance to be detected is determined, and an alarm is sounded. False detection can be prevented.
