GE AKTA avant - Second Column Valve

4.4 Second Column valve
Introduction
When using the ÄKTA avant standard configuration with one column valve, 5 column
positions are available. To increase the number of column positions to 10, an additional
column valve can be installed in the instrument. One application is for evaluation of a
number of different columns during method optimization.
Location and illustration
A recommended flow path is to move the Column valve (V9-C or V9H-C) to the free upper
position (Fig A) and to install the second Column valve (V9-C2 or V9H-C2) in the previous
position of Column valve V9-C or V9H-C (Fig B).
