  • Electrode with reversibly sealed fluoride sensing crystal
    Patent number: 6579434
    Abstract: A free fluoride ion sensitive electrode with longer service life can be obtained by eliminating the use of any cement or similar adhesive to hold the fluoride sensing crystal of the electrode in place within the rest of the structure of the electrode, using instead a pressure sealed combination of the fluoride sensing crystal and upper and lower elastomeric gaskets. This arrangement also permits replacing the crystal and sealing gaskets if needed, without replacing any of the other components of the electrode.
