6. Set the
Purge Rate
to 2.0 mL/min for a capillary IC pump and
6.0 mL/min for an analytical IC pump. Set the
Duration
to 1800 s.
7. Click the
Prime
button. A warning message asks you to verify that the
purge (priming) valve is open. Click
Execute despite warnings
(Chromeleon 7) or
OK
(Chromeleon 6.8). Priming starts.
8. Prime the pump until all air is purged and no air bubbles can be seen
exiting the waste line. Click the
Prime
button to stop priming.
NOTE
Priming will stop automatically after the number of
seconds specified in the
Duration
box is reached.
9.
Gradient pump only:
To prime additional eluent lines, select another
eluent channel and repeat the priming procedure.
10. Close the priming valve by turning the knob clockwise. Tighten no more
than fingertight.

Checking the Conductivity of the Water
For a CD system, check the background conductivity of the water before
continuing.
1. Connect a short piece of tubing to the CD cell inlet port.
2. Connect a luer adapter to the tubing and use a 1 mL syringe to flush fresh
deionized water through the cell.
NOTE
A luer adapter is shipped with the EGC.
3. Verify that the conductivity is 1
S or below. If the conductivity is greater
than 1
S, refill the reservoir with fresh water or use water from a
different source and then recheck the conductivity.
Do not use any tools to tighten the priming valve! Overtightening may
destroy the cap seal. Open or close the priming valve only when the
system pressure is down.
