the programmed run length. This ensures that a late-eluting
peak is still collected.
Gradient Method Select the desired gradient method option.
•If the Linear method is selected, solvents A and B will be
mixed gradually from the last programmed %B until the
next programmed %B is reached. This method connects
the inflection points that define the gradient with a
straight line.
•If the Step method is selected, each %B value is held
until the next programmed %B is reached. Because the
%B values are held, the changes at each new value are
nearly instantaneous, producing a stepped appearance
on the plot area.
•If Isocratic is selected, the module will pump a single %B
mix throughout the run.
Enable Rapid Equilibration Select this option to turn on rapid
equilibration. When enabled, this time-saving feature pumps
solvent at the maximum flow rate during column
equilibration. Note that some column sizes and types might be
adversely affected by high flow rates.
4.3.10.4 Fraction Collector
Use this tab to configure the CombiFlash Torrent module to
control up to four Foxy R2 High Flow fraction collectors. This
tab is also used to configure the module for use with a
Fractionation Valve.
Foxy fraction collector(s) should be connected to the module
via an Ethernet cable. To communicate with each fraction
collector, the IP address settings on this tab must match the IP
address set in each fraction collector. Note that all IP
addresses must be unique.
NOTE: The optional Foxy R2 High Flow fraction collector does
not support DHCP. If you are adding the Torrent module with
optional Foxy R2 High Flow fraction collectors to your
organization’s network, a static IP address must be assigned
to each fraction collector. Contact your IT department for
assistance.
