Abstract: Détecteurs à réservoir unicellulaire ou multicellulaire comportant des sources lumineuses distinctes et un ou plusieurs capteurs par unité cellulaire. Ces détecteurs posssèdent une configuration qui permet à un échantillon liquide, de vapeur ou gazeux d'entrer dans le corps de la cellule et d'avoir une action réciproque avec la solution de détection pour détecter et quantifier une substance donnée. L'échantillon entre dans le détecteur par l'ouverture située dans le corps de la cellule, ouverture qui peut être recouverte d'une membrane pour contenir le réactif de détection et pour trier préalablement les substances entrant dans la cellule. Les cellules à réservoir peuvent être utilisées avec des substances de détection organiques, inorganiques ou biochimiques. Un détecteur chimique à réservoir comporte un corps de détecteur contenant un canal de cellule à réservoir autour duquel la source lumineuse et le capteur sont positionnés à l'intérieur du corps de la cellule. Une cellule à réservoir modulaire remplaçable contenant une solution de détection s'adapte parfaitement au canal du corps du détecteur et peut en être retirée aisément. Différentes cellules à réservoir amovibles peuvent être facilement insérées dans le corps du détecteur puis retirées. On décrit une variété de détecteurs permettant de détecter, par exemple, l'alcool, des drogues, des haloïdes organiques, du cyanure et des ions inorganiques.

Abstract: The invention relates to the identifying of not easily volatilized substances, in particular hazardous materials, in a gas phase. A measurement cell (2) and a gas supply device (14) connected to the measurement cell (2) are heated and a plasmonic surface (1) arranged in the measurement cell (2) is temperature-controlled such that the plasmonic surface (1) has a lower temperature than the measurement cell (2) and the gas supply device (14). The gas phase is guided through the gas supply device (14) into the measurement cell (2) in such a manner that the gas phase reaches the temperature-controlled plasmonic surface (1). Substances adsorbed from the gas phase on the plasmonic surface (1) are analyzed by an optical process. Surface-enhanced Raman spectroscopy or surface-enhanced infrared spectroscopy can be used as the optical process. Selectivity can be increased by combining both methods. Selectivity can be additionally increased by using a gas detector, preferably an ion-mobility spectrometer, along with one or both optical processes, and thus the false alarm rate reduced without loss of time.
