摘要： Firstly, the following check chip is set up into a heater: A check chip onto which a sample has been picked up by wiping out the surface of a check target, or a check chip formed by absorbing and collecting the sample into a filter. Here, the filter has been set up in a vibration-type or heating-type portable-type absorption probe in an attachment/detachment-capable manner. Secondly, a sample gas generated from the heated check chip is analyzed using a tandem-type mass spectrometer. This makes it possible to simplify the sample pick-up from various types of check targets, and to shorten the pick-up time and the checking time.

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.
