(54) Title (EN): DEVICE AND METHOD FOR DETECTION OF CANNABIS AND OTHER CONTROLLED SUBSTANCES USING FAIMS (54) Title (FR): DISPOSITIF ET PROCÉDÉ DE DÉTECTION DE CANNABIS ET D'AUTRES SUBSTANCES RÉGLEMENTÉES À L'AIDE D'UN SPECTROMÈTRE FAIMS
(57) Abstract: (EN): A system for collecting cannabis and the psychoactive component tetrahydrocannabinol or other controlled substances from a sample of exhaled breath. Single or multiple exhaled breaths are conditioned by removing contaminants, and regulating flow rate and/or pressure to collect a sample of tetrahydrocannabinol for timely local or remote analysis using FAIMS. The cannabis detection system comprises a containment trap tor removing interfering materials from the breath of the subject and a collection component for sampling components of breath introduced into the system through the containment trap for FAIMS analysis to determine the level of THC or other controlled substance in the breath. (FR): La présente invention concerne un système pour la collecte du cannabis et de son composant psychoactif, le tétrahydrocannabinol, ou bien d'autres substances réglementées, à partir d'un échantillon d'air expiré. Une seule ou plusieurs expirations sont conditionnées par élimination des contaminants, et régulation du débit et/ou de la pression pour recueillir un échantillon de tétrahydrocannabinol en vue d'une analyse locale ou à distance effectuée en temps voulu au moyen d'un spectromètre FAIMS. Le système de détection de cannabis comprend un piège de confinement pour éliminer les substances interférentes contenues dans l'haleine du sujet et un composant de collecte pour échantillonner les composants d'haleine introduits dans le système par l'intermédiaire du piège de confinement à des fins d'analyse par le spectromètre FAIMS en vue de déterminer le taux de THC ou d'une autre substance réglementée dans l'haleine.
