Direct Control
Operation
The operation which shall be performed can be selected from the pull
down menu. The choices are waste, peak recycling, or solvent recycling.
It will be executed by clicking on the Set button.
Collect to
The operation fraction collection can be initiated here. The destination
vial is either defined as next, or in case of collect to by its number. The
collection starts by clicking on the Go button.
Run Time Settings
All operations started in the direct control mode are performed
unconditioned as timed events. For consecutive conditioned runs the
values for level, slope and the expected interval will be stored according
the settings. However, in any case it is recommended to check the
automatically stored fractionation program before using it.
Rack View
The displayed rack corresponds to the configured one. All already used
vials will appear green highlighted. Moving the cursor across the rack will
change the upper descriptive line. There the vial number, the begin and
end of collection and the collected volume is displayed (see the arrows in
Fig. 354).
Multi valve fraction collector
For this fraction collector the rack view is integrated into the instrument
status tab. The shape of the rack view again depends on the configured
valves. If different valves (6, 12, or 16 positions) are combined the
graphical separation may not be shown. The number of displayed
positions also may succeed the actual existing number of collection
positions, due to the rectangular arrangement.
