Abstract

L'invention concerne un procédé et un appareil de détection de produits volatiles dans un échantillon à l'aide d'un transducteur changeant de tension en fonction du contact des produits volatiles avec le transducteur, afin de produire une signature de gaz des produits volatiles, et d'un spectrophotomètre permettant d'analyser les produits volatiles afin de produire une empreinte spectrale des produits volatiles. L'appareil et le procédé sont utilisés pour détecter l'altération d'une matière biologique, telle qu'un aliment. L'appareil est aussi utilisé pour détecter des micro-organismes contaminant un produit alimentaire ou un échantillon environnemental et par comparaison de la signature de gaz et de l'empreinte spectrale à une banque de signatures de gaz et à des empreintes spectrales, l'appareil permet l'identification des micro-organismes et en particulier l'identification de micro-organismes pathogènes.
