5. Using a moist piece of polishing cloth (with no polishing compound
added), rub the polished surface free of residual polishing compound
particles.
6. Inspect the surface of the working electrode to make sure that it is
clean. Repeat Step 5
, if necessary.
NOTE The polishing pads are reusable. Do not rinse
the polishing compound from the pads. After
initial use, add only enough polishing
compound to maintain the coating on the pad.
7. Replace the working electrode block and PEEK yoke knob.
Fingertighten the knob by turning it a full 360 degrees.
NOTE It is not possible to overtighten the PEEK yoke
knob. Once the knob clicks into place, it does
not tighten any further. The PEEK yoke knob
ensures constant pressure is applied to the cell.
8. Orient the cell assembly with the PEEK yoke knob on the left and
push the cell onto its mounting location in the DC compartment.
9. Reconnect the cell’s inlet and outlet lines.
10. Reconnect the electrical cables.
11. Start the pump flow.
12. Wait until the pump pressure has stabilized (30 to 60 seconds) and
then turn on the cell voltage.
13. Reapply the electrode potential. The baseline will drift for more than
1 hour as the cell re-equilibrates. Peak area values may require up to
12 hours to stabilize.
