Patent ID: 8752411

Claim:
A device for measurement of volatile substances, comprising a containment box, having at least one inlet opening for introduction of a gas flow, one or more outlet openings of said gas flow and at least one analysis opening, one or more detection sensors arranged within said containment box, and at least one probe, insertable within said containment box through said at least one analysis opening, wherein a dimension of a port of said analysis opening is smaller than a dimension of a sum of ports of said one or more outlet openings, so that insertion or extraction of said probe from said analysis opening does not change the flow of said gas that reaches said sensors, said device further comprising a body arranged within said containment box, said body being provided with a through channel that has a first end communicating with said analysis opening and a second end communicating with the interior of said containment box, wherein said body is radially provided on its surface with one or more channels, in a number corresponding to a number of said one or more detection sensors, said channels being located on a lateral wall of said body and being suitable for partialization of gas flow toward each detection sensor, so that, when said probe is treated beforehand by a sample of a substance to be examined and is inserted within said containment box, said gas flow uniformly carries the volatile substances from said sample to said one or more detection sensors.
