Device for collecting a sample of elements of interest present as traces in a pressurized gas

Abstract : The present invention relates to a device for collecting a sample of elements of interest present as traces in a gaseous fluid, flowing under pressure in a pipe, said device comprising: - a mounting comprising an inner wall delimiting a sealed cavity, each of the ends of the mounting comprising an opening for the passage of the gaseous fluid allowing the passage of the gaseous fluid; a tube arranged in the sealed cavity, a medium for trapping elements of interest being arranged inside the tube; - the 2 ends of said tube being held in position in said cavity by holding means, the size of said cavity being configured so that the outer wall of said tube and the inner wall of the mounting delimit an annular free space defining the smallest possible vol.; - said holding means and the arrangement of said tube in the sealed cavity being configured to allow the passage of part of the gas into the annular free space when the gas enters the device to bring the annular space to the same pressure as the inside of the tube.
