MODE OF RECEIVING OF HIGHLY SENSITIVE POTENTIOMETRIC SENSORS Russian patent published in 2007 - IPC G01N27/416 

FIELD: the invention refers to the methods of manufacturing of highly sensitive ionometric sensors with a conductive film in quality of a sensitive element.

SUBSTANCE: the mode of receiving of highly sensitive potentiometric sensors includes the following operations: preparation of water solution for electrochemical polymerization containing monomeric links of conductive polymer in concentration from 0,002 to 0,05 M and a supporting electrolyte fulfilling also functions of alloying admixture whose concentration is from 0,0001 to 0,005 M: assembling of a tank for electrochemical polymerization containing solution for electrochemical polymerization, an auxiliary electrode, one or more working electrodes on which a covering out of conductive polymer is put on, putting on the working electrode(s) of polymer film by way of electrochemical synthesis of the polymer out of the solution for electrochemical polarization with using of at least one of the proposed electrochemical regimes.

EFFECT: creates on a basis of a polymer highly sensitive and reproductive potentiometric sensors stable during a long period of time.
