2.13 Setting the Pump Flow Rate (ICS-90A only)
NOTE The instructions in this section apply to the ICS-90A
only. If you are unsure whether your system is an ICS-90
or ICS-90A, check the model data label on the rear
panel.
The ICS-90A has a feature that allows the approximate flow rate to be displayed
on the Control panel in Chromeleon or Chromeleon Xpress. The accuracy of the
displayed flow rate depends on the flow rate at which the system was calibrated
and the current pump pressure.
The ICS-90A flow rate is calibrated at the factory before shipment and does not
need to be calibrated now. However, if you will typically operate the ICS-90A at a
particular flow rate, you may wish to calibrate the system at that flow rate to
improve flow rate accuracy. For instructions, see the
ICS-90 Ion Chromatography
System Operator’s Manual (Document No. 031851). The manual is included on
the Dionex Reference Library CD-ROM (P/N 055405).
To set the pump flow rate:
Pull out the flow rate knob on the component mounting panel (see Figure 2-18 )
and turn the knob until the desired flow rate is displayed on the ICS-90A Control
panel in Chromeleon or Chromeleon Xpress.
2.14 Equilibrating the System
1. After priming the pump and adjusting the flow rate, leave the pump on and
flush the system for about 5 minutes to equilibrate.
2. Monitor the system pressure from the ICS-90 (or ICS-90A) Control panel to
make sure the pressure is between 107 and 153 MPa (1600 and 2300 psi). If
the pressure is less than 107 MPa (1600 psi), gas may be trapped in the
system. Release the gas by opening one fitting at a time from the pump head
and along the plumbing to the column; pay close attention to the line from the
pulse damper (see
Figure 2-18 ).
3. Check that there are no leaks in the regenerant reservoir.
4. Check that liquid is flowing out of the suppressor
REGEN OUT
waste line and
that the pressure is stable.
