2. Remove the reference electrode from its box. Remove the electrode
from the storage bottle by partially unscrewing the cap and pulling
the electrode out of the opening in the cap. Save the bottle and cap.
Always store the electrode in the storage bottle filled with saturated
KCl solution when the cell is not in use. This prevents the reference
electrode membrane from drying out and damaging the electrode. See
Section 3.9 for storage instructions.
3. Rinse the electrode thoroughly in deionized water to remove any
precipitated salt. Go on to "Calibrating the Reference Electrode."
B.5.3
Calibrating the Reference Electrode
1. Make sure the detector is turned off and then connect the
amperometry cell cable to the cell and to the
SP card (see Figure 2-3.). Connect the other end to the cell's
electronics card (see Figure B-5).
2. Connect the reference electrode cable to junction J2 on the cell
electronics card (see Figure B-5).
3. Prepare two buffer solutions: one with a pH of 7.00 and one with a
different pH of your choice (for example, a calibration buffer that
closely matches the pH of the eluent to be used).
4. Turn on the detector and turn on the cell from the
