Description
Choose the fractionation type. See below for details.
Choose the outlet position for the first fraction. Subsequent
fractions will be directed to the next outlet position in numerical
order. Outflow after the last outlet position (determined by the
settings in Advanced Settings) will be directed to outlet 1-
Waste.
Applies to fractionation types with fixed volume fractions. Enter
the fraction volume.
Applies to fractionation types with peak fractionation. Specify
the peak detection conditions in Peak Frac Settings. If the col-
lected volume for one fraction reaches the value set in Peak
fractionation volume, outflow will be directed to the next
fraction. Set a large value for this parameter to avoid splitting
peaks into several fractions.
Fractionation will stop at the end of the phase, even if fraction-
ation in the next phase is set to Continue ongoing.
Note:
This setting is not available in Conditional Fractionation phases.
Description
Fixed volume fractions will be collected.
Fractions will be collected according to the peak detection
conditions in Peak Frac Settings. When no peak is detected,
flow is directed to Outlet 1-Waste.
Combines fixed volume and peak fractionation.
Fixed volume fractionation applies as long as a peak is not de-
tected. Peaks are collected as separate fractions according to
the peak detection conditions in Peak Frac Settings.
