FILTERING ASSEMBLY FOR FILTERING NANOPARTICLES COMPRISING A FILTER AND FILTER SUPPORT, APPARATUS AND METHOD FOR ASSEMBLING THE ASSOCIATED ASSEMBLY, AND METHOD FOR COLLECTING AND ANALYZING NANOPARTICLES THEREFOR.

摘要

The present invention relates to a filtration assembly for filtering nanoparticles, comprising: a filter (3) with pores able to retain within them nanoparticles that may be present in an air flow intended to pass through the filter, a filter support comprising two parts, of which: a bottom portion forming a base (2) having a peripheral surface on which the filter is able to be supported; . an upper portion in the form of a ring (1) adapted to be mounted around the bearing surface of the base, the mounting clearance between the ring and the bearing surface being dimensioned so as to maintain mechanical tension by pinching the filter, resting on the span, in a radial direction to the mounting direction.
