6. Press
PUMP PRIME 1
(or
PUMP PRIME 2
) on the front of the DP/SP. The
pump will begin pumping at the priming flow rate selected on the
Chromeleon panel.
7. Prime the pump until all air is purged and no air bubbles can be seen
exiting the waste line.
8. Gradient pump only: To prime additional eluent lines, select another
eluent channel and repeat the priming procedure.
9. After priming all eluent lines, press
PUMP PRIME 1
(or
PUMP PRIME 2
) to
stop priming and return to the flow rate last selected.
10. Close the priming valve by turning it clockwise. Do not overtighten the
priming valve.
11. Reconnect the pump to the software by clicking Connected on the Pump
panel.
9.5.2 Priming from the Chromeleon Panel
1. Open the priming valve on the secondary pump head (see Figure 9-2 ) by
turning it one-half turn counterclockwise.
NOTE
If the priming valve is opened too much, air is drawn
through the valve and air bubbles can be seen exiting
the waste line.
2. On the Chromeleon 7 ePanel Set or the Chromeleon 6.8 panel tabset, click
the Pump tab.
3. Gradient pump only: Enter 100% for the channel (A, B, C, or D) to be
primed.
4. Set the priming flow rate to the desired rate. The default rate for a
capillary IC pump is 3.0 mL/min. The default rate for an analytical IC
pump is 6.0 mL/min.
5. Click the Prime button on the Pump panel. 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.
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.
