The column compartment can hold one or two switching valves for advanced applications, including column switching. You can install the switching valves at the positions shown in Column Compartment Interior Components.

The following switching valve types are available:

  • Vanquish switching valves

  • VICITM switching valves

A mixed configuration of Vanquish switching valves and VICI switching valves is possible. You can install a Vanquish switching valve at any position where no VICI valve drive is installed.

When no valve is installed, a cover plate closes the opening.

Vanquish Switching Valves

The Vanquish switching valves consist of one part. The valve drive is integrated into the valve assembly.

To install a Vanquish valve, see Installing the Vanquish Switching Valve.

To replace a Vanquish valve, see Replacing the Vanquish Switching Valve.

VICI Switching Valves

The VICI valve consists of two parts, the valve pod (no. 1) and the valve lock ring (no. 2). The valve lock ring connects the valve pod to the valve flange (no. 3) of the valve drive. The valve drive is not integrated into the valve assembly. The valve drive is located inside the housing and cannot be accessed by the customer.

You can only install or replace the VICI valve. To install the VICI valve drive, contact your local Thermo Fisher Scientific Technical Support.
