ELECTROCHEMICAL GAS SENSOR WITH IONIC LIQUID AS AN ELECTROLYTE FOR DETECTION OF AMMONIA AND AMINES

摘要

1. An electrochemical gas sensor, comprising: an electrolyte containing an ionic liquid, wherein said ionic liquid contains at least one proton ammonium cation with at least one dissociable hydrogen atom, said at least one proton ammonium cation reacting with the target gas by deprotonation. 2. The gas sensor according to claim 1, characterized in that the target gas contains at least one component selected from the group consisting of: ammonia and amines. A gas sensor according to claim 1, characterized in that said gas sensor is designed to detect at least one predetermined gas selected from the group consisting of: ammonia and amines. The gas sensor according to claim 1, characterized in that said at least one proton ammonium cation has a pKa value less than about 9.25.5. The gas sensor according to claim 1, characterized in that said at least one proton ammonium cation is selected from the group consisting of: a monosubstituted ammonium cation; disubstituted ammonium cation; and a trisubstituted ammonium cation. 6. A gas sensor according to claim 1, characterized in that said at least one proton ammonium cation contains at least one substituent having at least one electron-withdrawing group. The gas sensor according to claim 6, wherein said at least one substituent having at least one electron withdrawing group contains at least one alkyl group selected from the group consisting of: branched C1-C20 alkyl groups; and unbranched C1-C20 alkyl groups; at least one aryl and / or
