Installing the pH-Ag/AgCl Reference Electrode

Preparing the pH-Ag/AgCl Reference Electrode
1. Orient the cell assembly with the yoke knob on the left and push the cell
onto its mounting location on the ED.
2. Remove the pH-Ag/AgCl reference electrode (P/N 061879) from its box.
3. Unscrew the storage cap from the electrode (see
cap.
Always store the pH-Ag/AgCl reference electrode in the storage cap
filled with saturated KCl solution when the cell is not in use. This
prevents the pH-Ag/AgCl reference electrode membrane from drying
out and damaging the electrode.

4. Rinse the pH-Ag/AgCl reference electrode thoroughly in ASTM Type I
(18 megohm-cm) filtered and deionized water to remove any precipitated
salt.
5. Calibrate the pH-Ag/AgCl reference electrode (see the next section).
Calibrating the pH-Ag/AgCl Reference Electrode
Items Needed
•
A buffer solution with a pH of 7
•
A second buffer solution with a different pH (typically one that matches
the pH of the eluent used in your application; for example, pH 10 or pH 4)
