B.13 Priming the Pump
1. Verify that the eluent and regenerant reservoirs are filled, the reservoir caps
are installed and hand -tightened, and the gas and liquid lines are connected to
the reservoirs (see Section B.10
).
2. Verify that the gas supply is turned on, the eluent reservoir is pressurized (see
Section B.12
), and the regenerant reservoir is unpressurized. Note: The
regenerant reservoir is unpressurized if the reservoirs are connected as
described in Section B.10
.
3. Verify that the waste lines are directed to a waste container.
4. To start the liquid flow, open the pump head waste valve (see Figure B-21
) by
turning the knob counterclockwise two turns. When the valve is open, eluent
flows directly from the pump to waste.
5. Let the liquid flow for at least 2 to 3 minutes to ensure that there are no
trapped gas bubbles in the line from the eluent reservoir to the pump head.
NOTE The factory set flow rate is 0.5 mL/min at 10 MPa
(1500 psi) of backpressure. Prime the pump at the
factory flow rate, and then go on to Section B.14
to set
the flow rate for your application.
6. Turn on the pump from the ICS-90 Control panel in Chromeleon. Allow the
pump to run with the waste valve open for 30 seconds.
7. Close the waste valve knob.
