摘要： A filtration assembly for filtering nanoparticles includes a filter having pores that can retain nanoparticles likely to be found in an air flow passing through the filter and a filter support including two parts. A lower base-forming part of the filter support includes a peripheral bearing surface on which the filter can rest. An upper ring-shaped part of the filter support is designed to be mounted around the bearing surface of the base. By mounting the ring around the bearing surface of the base it is possible to tension the filter radially to the direction of mounting. The mounting clearance between the ring and the bearing surface of the base is dimensioned such as to maintain the filter resting on the bearing surface under mechanical stress by means of pinching, in a direction radial to the mounting direction.

摘要： The present invention relates to a method for impregnating a filter having pores suitable for retaining particles within them that may be present in a flow of air suitable for passing through the filter, according to which the filter made up of a polymer membrane is impregnated with one or more organometallic salts by applying a treatment using supercritical CO2, the metal M of each salt being chosen from among the group of rare earths, yttrium, scandium, chromium, or a combination thereof. The invention also relates to the obtained filter and an associated method for the collection and quantitative analysis of nanoparticles.
