    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.

    摘要: A method and apparatus for analyzing vapors generated from explosives in which vapors containing nitrogen monoxide and/or nitrogen dioxide are generated by decomposing explosives by increasing the temperature of the explosives, primary ions and neutral molecules are generated from air. The generated primary ions and the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors are allowed to react with each other in an area inhibited or prevented from being penetrated by the generated neutral molecules, and the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors is ionized. The ionized nitrogen monoxide and/or nitrogen dioxide is subjected to mass spectrometry, and an amount of the nitrogen monoxide and/or nitrogen dioxide contained in the generated vapors by decomposing the explosives is determined.

    摘要: Mass transit terrorism is prevented to construct a safe society. Individual explosive sensing devices are connected by a network to establish a security system. Information collected in the security center is compared with a database to determine a risk. When the risk exceeds a predetermined level upon determination of the risk, measures may be taken such that an alarm is activated and instructions for making a security guard carry out the parcel inspection of the person causing the risk are transmitted to the security guard. According to the present invention, the security can be enhanced while the social life is still convenient even when the explosive sensing device having a high throughput is employed at places such as mass transit where many people gather. Therefore, the terror risk on the mass transit can be reduced to contribute to construction of the safe society.
