GAS-SENSITIVE DETECTOR Russian patent published in 2020 - IPC G01N27/12 G01N27/14 B82Y35/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas analysis, in particular to detecting devices used for recording and measuring various substances in a gaseous medium. Gas-sensitive detector has a carrier board with n microchips arranged thereon along the perimeter of the carrier board relative to each other at equal intervals, each microchip comprising a dielectric substrate, wherein on front side of dielectric substrate there arranged are gas-sensitive layer and contact pads connected to each other, on the reverse side of dielectric substrate there arranged are interconnected heating element and contact pads of heating element.

EFFECT: invention provides higher selectivity of detecting compounds comprising an odour owing to the possibility of using the required number of microchips, which can change analytical properties of different substances in gas medium at different heating temperatures, thereby forming unique images for a wide range of substances of different groups of chemical compounds.
