4.3.2.5 Peak Collection
Use the Peak Collection buttons to set the collection mode.
• All — Click this button to collect all fluids during a run.
• Peaks — Click this button to collect only eluted peaks
during a run.
• None — Click this button to divert all fluids to the
waste port during a run.
• Tube Volume — You can also specify the Tube Volume
for collected fluids. This volume can be the default
maximum volume (Max option) as entered in the
CONFIGURATION [4.3.10] window, or a method-specific
volume less than the capacity defined by the
CONFIGURATION [4.3.10] window. When using a Foxy
fraction collector or the Fractionation Valve, note that
the actual fraction size may be less if a newly detected
peak causes a tube change, or if you click the Next Tube
button.
• Peak — Type or select the desired volume to be
collected in each tube when the module detects a
peak.
• Non-peak — Type or select the desired volume to be
collected in each tube when peaks are not detected.
This setting allows you to conserve tubes without
diverting non-peak elute to waste. This setting is
ignored when the peak collection mode is set to Peaks
or None.
