If these procedures fail to rejuvenate the electrode, the problem is probably a clogged reference
junction in the reference electrode portion of the electrode system. Cleaning the reference junction
involves heating a diluted KCl solution to 60 - 80 degrees Celsius. Place the electrode tip in the heated
KCl solution for approximately ten minutes. Allow the electrode to cool naturally before re-testing. If
these steps fail to improve the electrode response, replace the electrode.
Successful long term storage of an InsiteIG electrode depends entirely upon the care taken to assure
that the glass and reference junction remain immersed in the recommended storage solution. Electrodes
in storage with the protective rubber boot should be checked at least every 2 months to be sure that
there is an adequate amount of storage liquid. Electrodes stored in this manner will normally last for 2
years. If a stored electrode is allowed to dry the reference junction may become clogged with dried
electrolyte. Should this occur, attempt to rejuvenate the reference junction using the "Cleaning
Electrodes" procedure for reference junctions discussed earlier.
