Electrode maintenance

Make sure the electrode is filled with electrolyte solution. Always store the electrode according to
the electrode instruction manuals and do not allow it to dry out.
If the electrode response becomes sluggish or the slope is not acceptable, try the following:
o
Soak the electrode in 0.1M HCl for at least 8 hours.
o
For fat or oil contaminant, degrease the membrane with cotton wool soaked in either
acetone or a soap solution.
After electrode treatment, a new calibration should be performed. If the electrode slope is still not
acceptable, the electrode might need to be replaced.
