Installing the 6-port valve

During sample preparation, the 6-port valve is used as a switch between
two different flows.

Connectors
The 6-port valve (like the injection valve) has six connections that can be
connected together depending on the application.

Connecting the 6-port valve

1 Connect all capillaries using PEEK pressure screws (6.2744.010).

Valve positions
The 6-port valve (see Figure 14, page 38) can have two valve positions:
Filling and Injecting. Switching is used to connect two different connec-
tions together in each case.
