A vapor collection method and apparatus capable of capturing vapor compositions without substantial dilution. The method and apparatus utilize a material (12) that has a surface (14) with an adjacent gas phase. A chamber (16) is positioned in close proximity to a surface (14) of the material (12). The position of the chamber (16) creates a relatively small gap (H) between the surface of the material (14) and the chamber (16). The adjacent gas phase between the chamber and the surface define a region possessing an amount of mass. At least a portion of the mass is drawn through the region by induced flow. The utilization of a small gap (H) limits the flow of mass that is external to the chamber (16) from being swept through the chamber by induced flow.

L'invention concerne un procédé et un appareil de collecte de vapeur capable de capturer des compositions de vapeur sans dilution substantielle. Ce procédé et cet appareil utilise un matériau (12) possédant un surface (14) avec une phase gazeuse adjacente. Une chambre (16) est positionnée à proximité d'une surface (14) du matériau (12). La position de la chambre (16) crée un petit intervalle (H) entre la surface du matériau (14) et la chambre (16). La phase gazeuse adjacente entre la chambre et la surface définissant une zone possédant une grande masse. Au moins une partie de cette masse est étirée dans la zone par flux induit. L'utilisation d'un petit intervalle (H) limite le flux de masse externe à la chambre (16) d'être balayé à travers la chambre par flux induit.
