A vacuum ultraviolet ray generating unit (5) which generates vacuum ultraviolet rays used for ionizing a sample gas Gs in an ionization chamber (1) and a mass spectrometry unit (6) which accelerates the sample gas Gsi ionized by vacuum ultraviolet rays so as to measure the flight time of the accelerated substance.
L'invention porte sur un dispositif de détection d'une substance chimique comprenant un générateur (5) qui génère des radiations ultraviolettes sous vide afin d'ioniser un gaz échantillon Gs dans une chambre d'ionisation (1), et un spectromètre de masse (6) qui mesure le temps nécessaire à une substance, accélérée par l'accélération du gaz échantillon Gsi ionisé par les radiations ultraviolettes sous vide, pour s'évaporer.
