Abstract

Dispositif de rétention de produits contenus dans l’air ambiant, et procédé correspondant. Dispositif de rétention (1) de produits contenus dans l’air ambiant, comportant des moyens d’aspiration de l’air ambiant, des moyens de réglage des moyens d’aspiration, un premier organe de rétention (3) de produits présents dans de l’air ambiant aspiré comportant une membrane poreuse, et un second organe de rétention (4) de produits présents dans de l’air ambiant aspiré comportant un récipient (5) contenant du liquide. Procédé d’analyse de l’air utilisant un tel dispositif de rétention (1), ce procédé comportant les étapes suivantes :- on positionne, dans le dispositif de rétention (1), une membrane poreuse dans un premier organe de rétention (3) et un récipient (5) contenant du liquide dans un second organe de rétention (4),- on actionne des moyens d’aspiration de l’air ambiant du dispositif de rétention (1) pendant un temps défini,- on extrait la membrane poreuse et le récipient (5) contenant du liquide. Figure pour l’abrégé : Fig.1Device for retaining products contained in ambient air, and corresponding method. Device for retaining (1) products contained in ambient air, comprising means for suction of ambient air, means for adjusting the suction means, a first retention member (3) for products present in the sucked ambient air comprising a porous membrane, and a second retention member (4) for products present in the sucked ambient air comprising a container (5) containing liquid. Air analysis method using such a retention device (1), this method comprising the following steps: - a porous membrane is positioned in the retention device (1) in a first retention member (3) and a container (5) containing liquid in a second retention member (4), - means of suction of ambient air from the retention device (1) are activated for a defined time, - the porous membrane is extracted and the container (5) containing liquid.
