Abstract: A method of quickly detecting a handmade explosive in a bottle with a low erroneous alarm frequency is provided. A sample gas generated from a bottle placed on a bottle placement space is sucked-in, and ions of the sample gas are generated by an ion source and subjected to mass analysis. The presence/absence of a mass spectrum derived from the handmade explosive is determined from an obtained mass spectrum, and the result thereof is displayed on a monitor, thereby quickly detecting the handmade explosive in the bottle or the handmade explosive adhering to the surface of the bottle at a low erroneous alarm frequency.
