Electronic nose with zeolite-coated sensors and closed-loop temperature control. It presents sensors based on tin oxide, coated with a zeolite molecular sieve, to improve the discrimination of volatile compounds in the substance to be analyzed. It also includes a closed-loop temperature control to improve the precision of the temperature at which the sensors are located, and an airtight chamber consisting of a two-piece cylindrical container that is joined by a thread that, due to its geometry, unifies the temperature. force with which the chamber is sealed. |
