11. Orient the cell assembly with the yoke knob on the left and then push the
cell onto its mounting location on the ED.
12. Connect the reference electrode cable and the cell cable.
13. Reconnect the cell inlet and outlet fittings.
14. Condition the PdH reference electrode (refer to the instructions below).
Conditioning the PdH Reference Electrode
Condition the PdH reference electrode after plumbing the cell:
1. On the Chromeleon 7ePanel Set or Chromeleon 6.8 panel tabset, select
the following settings:
a. Pump panel: Set the pump flow rate to 0.01 mL/min. This turns on
the pump flow, also.
b. EG panel: Enter 100 mM in the Target Concentration field. This
turns on the power to the EGC, also.
c. Verify that eluent is exiting the cell.
d. ED panel: Set the reference electrode mode to PdH .
e. Select DC amperometry mode, set the cell voltage to 0.000 V, and
turn on the cell voltage. Switch to integrated amperometry mode and
select the PdH-referenced carbohydrate waveform.
2. Condition the electrode for 1 hour at these settings.
3. Turn off the pump flow. This turns off the EGC power and the cell
voltage.
9.28.9 Replacing an ED Detector
1. Turn off the pump flow.
2. Press the
POWER
button on the front of the DC for 2 seconds to turn off
the DC.
3. Open the DC upper door and disconnect the cell inlet and outlet lines.
4. Disconnect the reference electrode cable and the cell cable.
5. Grasp the cell body and pull straight out to remove the cell from the
detector.
