Beschreibung
Zusammenfassung:	sensors used for monitoring chemical composition of air and gaseous media; selective recording of ammonia. SUBSTANCE: sensor showing content of gaseous ammonia in air includes ammonia-sensitive element fitted on dielectric substrate. Used as sensitive element is porous matrix impregnated with 7, 16 dibromodibenzotetraase-(14)- annulene of cobalt and/or nickel at its content in matrix of 1 to 40 mg/sq.cm or porous matrix impregnated with mixture of complexes of dibenzotetraase-(14)-annulene of cobalt and/or nickel with the following substituents: H, CN, Br and C6H5.. EFFECT: possibility of selective determination of content of ammonia in air as compared with vapors of volatile amines. 2 cl, 2 dwg
