Abdichtung fuer Fluid enthaltende Kammer

Abstract

DE 102009048607 A1 UPAB: 20110425 NOVELTY - The sealing allows a chamber (1) to be formed in a housing (5) that comprises a gasket (6) and/or a film (7) that divides the chamber into two cavities. Channels (2-4) opened in a direction of the gasket or the film is formed in parts (5.1, 5.2) of the housing at a region around the chamber. The channels are provided on or in the gasket. Inert purging gas or fluid removed from a measuring cell is conducted through the channels in such a way that the purging gas or the fluid immediately flows along a surface of the gasket and/or of the film. USE - Sealing for determining permeation rate of a film or solid within a chamber (all claimed). Uses include but are not limited to determine permeation rate of a film or solid for selected molecules e.g. water, oxygen or methane, or atoms of substances and/or chemical elements or chemical compounds. ADVANTAGE - The inert purging gas or fluid removed from the measuring cell are conducted through the channels in such a way that the purging gas or the fluid immediately flows along the surface of the gasket and/or of the film, thus avoiding penetration of substances into the chamber, and hence providing a secure sealing of the chamber against external influences
