(DE) VERFAHREN UND VORRICHTUNG ZUR ÜBERPRÜFUNG EINER GASPROBE
(EN) METHOD AND APPARATUS FOR INSPECTING A GAS SAMPLE
(FR) PROCÉDÉ ET APPAREIL POUR INSPECTER UN ÉCHANTILLON DE GAZ
Abstract
(EN)
An apparatus for detecting a presence of at least one analyte in a gas sample. The apparatus comprises a pump for drawing a gas sample from an ambient air, a passage having first and second ends, a chamber connected to the first end and containing a concentrating element for collecting at least one analyte from the gas sample, a chromatographic separator connected to a second end of the passage, and a gas source for streaming a carrier gas via the chamber to transfer the at least one analyte toward at least one chemical detector, via the chromatographic separator, in a first direction. The pump draws the gas sample via the chamber in a second direction and the first and second directions are substantially opposing to one another.

(FR)
L'invention porte sur un appareil pour détecter une présence d'au moins un analyte dans un échantillon de gaz. L'appareil comprend une pompe pour aspirer un échantillon de gaz à partir de l'air ambiant, un passage comportant des première et seconde extrémités, une chambre reliée à la première extrémité et contenant un élément de concentration pour recueillir au moins un analyte à partir de l'échantillon de gaz, un séparateur chromatographique relié à une seconde extrémité du passage, et une source de gaz pour produire un courant d'un gaz porteur à travers la chambre afin de transférer le ou les analytes vers au moins un détecteur chimique, par l'intermédiaire du séparateur chromatographique, dans une première direction. La pompe aspire l'échantillon de gaz par l'intermédiaire de la chambre dans une seconde direction, et les première et seconde directions sont sensiblement opposées l'une à l'autre.
