Dionex ICS-4000 Installation Instructions
To prepare the pH-Ag/AgCl reference electrode
1. Remove the pH-Ag/AgCl reference electrode (P/N 061879) from its box (see
Figure 54. pH-Ag/AgCl reference electrode in storage cap
IMPORTANT The ICS-4000/5000 ED pH-Ag/AgCl reference electrode
(P/N 061879) is similar in appearance to the Dionex AS-AP pH electrode
(P/N 075529). However, these two electrodes are not interchangeable. Before
continuing, check the label on the electrode to verify that you have the correct type.
2. Hold the electrode vertically, with the cable up and the storage cap down, to prevent
spilling the storage fluid in the cap. Unscrew the storage cap from the electrode. Be
careful not to spill the contents. Save the cap.
IMPORTANT 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.
3. Rinse the pH-Ag/AgCl reference electrode thoroughly in ASTM Type I (18 megohm-cm)
filtered and deionized water to remove any precipitated salt.
