PICKUP OF AMMONIA CONTENT IN AIR Russian patent published in 2003 - IPC

FIELD: measuring equipment, monitors of chemical composition of air gaseous media, applicable for monitoring of ammonia content. SUBSTANCE: the pickup of ammonia content in air has an element sensitive to ammonia, located on a dielectric backing provided with a system of electrodes. The pickup uses as a gas-sensitive substance complexes of 3-, 4-, 5d transition element of Mn, Fe, Co, Ni, Cu, Pd, Pt with oxime α-benzoinoxime and 4-nonylaldoxime or dioxime diacetyldiaxime having aromatic substituents C₆H₅ or aliphatic substituents CH₃ and C₉H₁₉. EFFECT: enhanced sensitivity to determination of ammonia in air media. 2 dwg
