Column Switching
The DuoFlow system supports the use of more than one column during a run. (Chapter 9
provides two examples of column switching during a run.) Use this button to specify which
column to load sample onto.
Column switching between as many as eight columns can be done with two AVR9-8 valves. A column switch
valve is defined by pressing Column Switching in the device setup and assigning two AVR9-8 valves to the
column switching valve. This identifies the two valves as installed and synchronizes the switching of the
valves without further user input. Column switching permits identification of the electrical connection port of
each valve and user naming for each column. Installation of the AVR9-8 valve in setup automatically
activates Column Switching in the Protocol screen.
• Position: Select the column to switch to in a run.
• OK: Adds the step to the protocol. This is the same as pressing the Enter key on the keyboard.
• Cancel: Does not add the step to the protocol. This is the same as pressing the Esc key on the
keyboard.
• Step, Time or Volume: Identifies current step number, and calculates the elapsed time or volume from
all previous steps. This is not user editable.
