- Store the electrode as mentioned above (see section Storage).
2.5. Electrolyte Replacement (for refillable electrode only).
The reference electrolyte needs to be refilled when the electrode has been
used for a long period, or when the internal electrolyte has dried up. To
accomplish this, follow the procedure described below.
- Remove the protective rubber cap or sleeve;
- Remove the protective rubber sleeve to expose the filling port of the
electrode;
- Remove the old reference electrolyte with a syringe;
- Fill the new reference electrolyte.
2.6. New electrolyte preparation:
- Open the KCl container;
- Add in de-ionized water until it reaches the level of 20 ml;
- Close the container and shake it to dissolve the KCl;
- Add in fresh electrolyte until it reaches the level of the refilling port. The
reference electrolyte used should be 3M(Mol) KCl;
- Replace the rubber sleeve.
2.7. Re-use the electrode.
- Rinse the liquid junction with de-ionized water.
If these steps fail to restore normal electrode response, you may attempt to
rejuvenate it (See: Electrode Rejuvenation).
2.8. Electrode cleaning
Electrodes which are mechanically intact can often be restored to normal
performance by one or combination of the following procedures.
- Salt deposits:
Dissolve the deposit by immersing the electrode in tap water for ten to fifteen
minutes. Then thoroughly rinse with de-ionized water. Wash the electrode pH
bulb in a little detergent and water. Rinse electrode tip in with de-ionized
water.
- Oil/Grease films:
Wash electrode pH bulb in a little detergent and water. Rinse electrode tip
with de-ionized water.
- Clogged Reference Junction:
