6. Turn on the pump from the ICS-90 (or ICS-90A) Control panel in
Chromeleon or Chromeleon Xpress. Allow the pump to run with the waste
valve open for 30 seconds.
7. Close the waste valve knob.
2.12 Setting the Pump Flow Rate (ICS-90 only)
The instructions in this section apply to the ICS-90 only. If you are unsure
whether your system is an ICS-90 or ICS-90A, check the model data label on the
rear panel.
2.12.1 Setting the Flow Rate
1. Locate the production test chromatogram on the Dionex Quality
Assurance Report (supplied with the separator column). Note the
backpressure and flow rate listed for the column.
2. Pull out the flow rate knob on the component mounting panel (see
) and turn the knob slowly to the right to begin adjusting
the pressure.
NOTES
•
There is about a 10-second delay between adjusting the knob and
the pressure reading response on the ICS-90 Control panel in
Chromeleon or Chromeleon Xpress.
•
The flow rate on the ICS-90 Control panel is a recorded value only
and does not change when the flow rate knob is adjusted.
3. Adjust the knob until the pump pressure reading on the ICS-90
Control panel reaches the figure listed on the production test
chromatogram.
NOTE The production test chromatogram is produced
without a guard column. If a guard column is
installed, adjust the knob until the pressure is about
1.4 to 2.1 MPa (200 to 300 psi) above the
backpressure listed for the separator column alone.
