3. Open the DC upper door and disconnect the tubing from the CD
CELL IN
and
CELL OUT
ports (see Figure 9-51 ).
4. For an analytical CD, remove the suppressor from the detector. For
instructions, refer to Section 9.27.2 .
5. Press the release lever located below the detector (see Figure 9-51 ). The
detector pops out slightly from the DC compartment. Grasp the top of the
detector and pull outward to remove the detector from the compartment.
Do not pull from the
CELL IN
and
CELL OUT
fittings .
6. Note the electrical plug on the back of the detector and the receptacle on
the inside of the DC.
7. Push the new detector into the opening in the DC and press firmly to
ensure the electrical connection is secure.
8. Reconnect the cell inlet and outlet lines.
9. Reinstall the suppressor (see Section 9.27.2 ).
10. Turn on the DC power and restart the pump flow.
9.27.4 Removing Trapped Air from the Conductivity Cell
Air bubbles in the cell can cause pulsations of the baseline, random noise, and
low readings. Air may result from outgassing of the eluent. In an analytical IC
system follow the steps below to remove trapped air from the cell. These steps
are not required for a conductivity cell in a capillary IC system.
