160 Setting Gradient Controller Operating Parameters
8.2.2 Setting Pump Setup Parameters
This section describes the pump parameters and provides procedures for setting each
parameter on the Pump Setup screen.
The pump parameters are:
• Reservoirs to sparge
• Pump col. temp. heater limit
• Press limits
• Chart out
•Flow factor
• Autostart
• Keyboard lock/unlock
Reservoirs to Sparge
Indicates which reservoirs you want to enable for helium sparging. The Reservoirs to
Sparge parameter only enables a reservoir for sparging; it does not initiate the sparging
process. The sparge flow rate can be set on the Isocratic, Event, or Operate Gradient
screen, depending on the mode of operation.
If helium is unavailable or undesirable for sparging, see Appendix B, Eluent
Considerations, for alternative degassing methods.
To configure the reservoirs to sparge:
1. Move the cursor to the field for the reservoir that you want to sparge.
2. Type 0 to disable sparging, or 1 to enable sparging for that reservoir.
3. Press Enter.
4. Repeat steps 1 through 3 for each active reservoir that you want to sparge.
Pump Col. Temp. Heater Limit
Defines the high-temperature limit for the optional column heater. The upper limit of the
heater module is indicated on the module label.
Note: To prevent damage to the column, the heater module shuts down when the
temperature exceeds the programmed limit for more than 1.2 seconds.
