Abstract: A device for collecting exhaled breath allows a substantial air washing of the whole device which allows its re-use, after replacing the disposable portions. The device includes: a collecting terminal, having a mouthpiece grip which receives the exhaled breath; at least one collecting hole, for collecting a portion of exhaled breath from the collecting terminal, to be subjected to examination; least one discharge vent; and an aspirator device, which is connected to the at least one discharge vent of the collecting terminal through a respective discharge duct, and which includes at least one nanometric filter through which the exhaled breath sucked through is purified.

Abstract: A filtering and adsorbent sampling and enrichment system comprising a stationary phase consisting of a felt of activated carbon fibres with a micro-meso porous conformation and specific surface area of about 1500 m2/g and sampling and/or enrichment standards, confined within a closed casing, is described, as well as the method for obtaining it and the relative process for the analysis of organic and inorganic analytes that uses said system.
