LIQUID ELECTROLYTE FOR ELECTROCHEMICAL GAS SENSOR Russian patent published in 2017 - IPC G01N27/404 

FIELD: chemistry.

SUBSTANCE: for liquid electrolyte used in electrochemical gas sensor for detecting NH₃ or NH₃ - containing gas mixtures, the present claim provides that said electrolyte contains at least one solvent, one conductive salt and/or one organic mediator. Wherein the conductive salt represents an ionic liquid, an inorganic salt, an organic salt, or a mixture of these substances. Preferably, the electrolyte consists of (i) water, propylene carbonate, ethylene carbonate or mixtures thereof as the solvent; (Ii) LiCl, KCl, tetrabutylammoniatoluenesulfonate or 1-hexyl-3-methylimidazolium tris (pentafluorethyl) trifluorophosphate as conductive salt; and (iii) tretbutylhydroquinone or anthraquinone-2-sulfonate as an organic mediator.

EFFECT: improved properties.
