1. A special drug detection method, comprising:
- a step of applying a vibration to a check target,a step of absorbing, as a sample gas, the air on surface of or in proximity to said check target,a step of ionizing said absorbed sample gas,a first analysis step of analyzing masses of ions of said ionized sample gas thereby to acquire mass spectrums thereof,a first judgment step of judging whether or not ions having a first characteristic m/z value are present on the basis of said mass spectrums acquired at said first analysis step,a second analysis step of performing a tandem mass spectrometry in correspondence with a judgment result acquired at said first judgment step, anda second judgment step of judging whether or not ions having a second characteristic m/z value are present on the basis of mass spectrums acquired by said tandem mass spectrometry.

Abstract
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.
