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 3 to be mixed with a sample gas for introduction into an ion source 4 for ionization, thereby obtaining a mass spectrum by a mass analysis region 5. A data processor 6 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.

摘要： A gas monitoring apparatus capable of real-time detection of a kind of chemical warfare agent, namely diphenylcyanoarsine (DC) and/or diphenylchloroarsine (DA). Atmospheric pressure chemical ionization mass spectrometry is carried out in the positive ionization mode, the total amount of DC and DA is determined from the intensity of an ion common to DC and DA, the DC concentration is determined from the intensity of an ion specific to DC, and the difference between them is regarded as the DA concentration.

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： A gas monitoring apparatus includes a sample introducing portion, a measurement portion, an ionization portion, a mass analysis portion, a data processing portion and a display. The sample introducing portion introduces a sample gas including an object material to be measured. The measurement portion measures a concentration of a predetermined coexisting material, which coexists with the object material in the sample gas. The ionization portion ionizes the sample gas. The mass analysis portion analyzes mass of an ion produced by the ionization portion. The data processing portion analyzes signals detected by the mass analysis portion to calculate a concentration of the object material. And the display displays results of analysis conducted by the data processing portion. The data processing portion includes an adjustment portion which adjusts the concentration of the object material according to the concentration of the predetermined coexisting material.
