Abstract
Disclosed is an electrode design which exhibits extended service live when immersed in aqueous fluoride ion containing compositions. The electrode comprises a fluoride ion sensitive membrane adhered to an insulating electrode shell by means of a slow-setting cement. At least one deposit of a cyanoacrylate glue adheres to the membrane and the electrode shell so as to prevent contact between the aqueous composition and the slow-setting cement.
Claims2
An extended-life electrode suitable for measuring the concentration of fluoride ion in an aqueous solution comprising an insulating electrode shell having an aperture therein, a fluoride sensitive membrane adapted to cover said aperture, a layer of slow-setting cement located between the membrane and the perimeter of the shell aperture and adherent to both the membrane and shell and means for isolating the slow-setting cement layer from the solution comprising a cyanoacrylate glue adhered to the membrane and the shell.
