Instr
Instr (Instrument) keys: These keys allow you to select individual instruments to
control. The selected component is indicated by its corresponding LED on the front
panel and its corresponding control screen is displayed. Note that the Pump,
Collector, and Alarm keys are grouped in a shaded area, indicating that these func-
tions (pump operation, fraction collection, and alarms) are programmed as part of a
separation method. Valve Buffer Select and Divert functions are programmed in a
method, but Bypass functions are only selectable in Manual mode. All other func-
tions are
not programmed as part of a method, but may be selected prior to and
during a run.
•
Pump: Allows you to set the flow rate and buffer mixture for the BioLogic LP
pump. Pump operating conditions are programmed as part of a method.
•

Collector. Fraction collection is programmed as part of a method.
•
Alarm: Allows you to set the timer for the Alarm. Alarm values are pro-
