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.

1. Field of the Invention
The present invention relates to detection technologies for gunpowder-kind materials such as explosive substances, dangerous objects such as flammable substances, poisonous gases, and legally prohibited medications such as drugs (all of which, hereinafter, will be generically referred to as “special drugs” for convenience). More particularly, it relates to a detection method and its device that, by using a mass spectrometer, detect whether or not a special drug is present inside, e.g., baggage such as a piece of hand baggage, freight, and a suspicious object.
