| 摘要 |
The present invention provides a method for analyzing vapors generated from explosives, capable of collecting a sample with ease, and stably analyzing the vapors generated from explosives in a short time and with high accuracy, and an analysis apparatus to be used for the analysis method. The analysis method of the present invention, comprises the steps of: generating vapors from explosives; generating primary ions and neutral molecules from air; allowing the generated primary ions and an analysis target sample contained in the generated vapors to react with each other in an area inhibited or prevented from being penetrated by the neutral molecules generated, and ionizing the sample; and subjecting the ionized sample to mass spectrometry. The analysis apparatus of the present invention, comprises an air generating means; an atmospheric pressure ionization means; and a mass analysis means, wherein the atmospheric pressure ionization means has a corona discharge unit, and an ionization reaction region for allowing the primary ions and the analysis target sample to react with each other, and has a neutral molecule penetration inhibiting means for inhibiting or preventing the penetration of the neutral molecules in the ionization reaction region.
