Detection method and detection device of special drugs
View Patent ↗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. 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, and
a 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.
2. The special drug detection method according to claim 1 , further comprising a step of outputting a judgment result in correspondence therewith, said judgment result being acquired at said second judgment step.
3. The special drug detection method according to claim 2 , wherein said judgment-result outputting step is a notification step of issuing an alarm.
