Flow Rate
The flow rate can be set to 0.00 (which turns off the pump) and to between 0.05
and 5.00 mL/min. The recommended operating flow rate is between 0.40 and
2.00 mL/min. Refer to the column manual for the flow rate to use with your
column and application. Column manuals are included on the Dionex Reference
Library CD-ROM (P/N 053891).
Pump On/Off Control
Touching the On button immediately starts the pump flow at the rate displayed in
the Flow Rate field. Touching Off stops the flow.
Prime
The Prime button is reserved for use during the pump head priming procedure.
Touching the Prime button displays a confirmation page that reminds you to open
the waste valve. Open the valve, and then touch the OK button to begin priming.
Or, to exit the page without priming, touch the Cancel button. To stop priming,
touch the Off button. During priming, the flow rate is approximately 3 mL/min.
See Section B.13 for detailed priming instructions.
Eluent Level
Use this field to monitor the amount of liquid in the eluent reservoir. When you
fill the reservoir, enter the amount of liquid in the reservoir. For example, if the
reservoir contains 200 mL and you add 1 liter, enter 1.2 liters. Thereafter, the ICS-
2100 determines the eluent usage by monitoring the flow rate and the length of
time the pump is on. The ICS-2100 updates the
Eluent Level field as the eluent is
depleted. A warning first appears if the level falls below 200 mL. Warnings are
repeated at 100 mL and 0 mL.
In order for the eluent level displayed on the screen to be accurate,
the level must be entered by the user when the reservoir is filled. The
ICS-2100 does not automatically detect when the reservoir is filled,
nor when it is empty.
