Action
Connect port E on the Loop valve to port LoopE on the Injection valve.
Connect port F on the Loop valve to port LoopF on the Injection valve.
Connect one or many loops to the Loop valve. See Section 5.7 Sample appli-
cation, on page 189.
Note:
Always use the the first positions of the valve for the connected loops (e.g., if
three loops will be used, use port 1F-3F and the corresponding ports 1E-3E)
to avoid cross-contamination.
It is possible to place the Loop valve in other positions in the flow path than
the one described above. However, the volume used for washes will then be
incorrect, just as the system configuration shown in the process picture.
