Virtual Fraction Collector Configuration
Fig. 324 Virtual fraction collector configuration window
The virtual fraction collector is a tool to optimize the fractionation without
need for sample or eluents. Therefore, only opening and closing the
configuration window would be sufficient. However you have two areas
for individual settings. .
Rack Type
Select from the drop down list that rack type best in comparison with your
real one. The choice is the same as for the Büchi fraction collector: Micro
with 240 vials, standard with 120, and preparative with 48 positions. The
Vials number will be displayed automatically.
Vial Volume [ml]
The rack dependent value will be displayed automatically. However, you
are allowed to overwrite it by self-defined values. If any fraction is larger
than the set volume the next free collection position will be used for
continued collection.
Tubing Parameters
These settings enable someone to consider the time delay for
transporting the sample from the flow cell to the collector valve. Here you
can adapt it to the real conditions of your system.
The solvent and peak recycling options you cannot simulate.
