Function
The column valve module consists of a number of membrane valves to control the flow
path, and two integrated pressure sensors to monitor the pressure over the columns.
The illustrations below show schematic flow paths inside the column valve module (left),
and a list of options (right). This list is located in the Column valve dialog box accessible
from the Process Picture.
The positions marked P in the left illustration below indicate the pre-column and post-
