Recently, the accident because of drunken driving is taken up in the topic of news, and the concern is had at the amount of the drinking and the drinking time etc. of the inside of the body. It is said that there is a correlation in the alcoholic density included in an alcoholic amount and the expiration in blood so far, and is reported on the equipment that measures an alcoholic density of the expiration based on this. We also are executing the breath analysis as an example of applying QMS (four pile polar mass spectrometer) gas analyzer "Gravimas". This time, an alcoholic density in the expiration was measured, the performance of this device to alcoholic detection was examined, and the change at the time of an alcoholic density in the expiration high sensitivity was measured. These results suggest the utility of the breath analysis that uses QMS.
