Key Description
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: Allows you to set the operating conditions for the Fraction
Collector. Fraction collection is programmed as part of a method.
• Alarm: Allows you to set the timer for the Alarm. Alarm values are pro-
grammed as part of a Method.
• UV: Allows you to set the operating conditions for the UV monitor. UV set-
tings may not be programmed as part of a method, but may be changed dur-
ing a run.
• Cond: Allows you to set the operating conditions for the BioLogic LP
Conductivity Monitor. Conductivity settings may not be programmed as part
of a method, but may be changed during a run.
• Valves: Allows you to set the operating conditions for the BioLogic LP Valves.
The SV-3 Diverter valve and SV-5 Buffer Select valve functions are controlled
by the method program; the SV-3 Bypass function is not programmed as part
of a method.
• Recorder: Allows you to start/stop the Bio-Rad Model 1327 Chart Recorder.
When a method is run, the chart recorder automatically starts when the
method begins and stops (pens lift up) when the method ends. Pressing the
Recorder key on the front panel during a run can start/stop chart recorder
activity.
