The Vanquish valve and the VICI valve each have one drain hole.

When

  • Liquid droplets appear at the drain hole

  • Liquid has collected in the leak tray

Follow these steps

  1. As leakage usually occurs at a connection, visually inspect all connections in the flow path.

  2. Remove the capillaries and install them again.

  3. Tighten all connections in the flow path.

  1. Inspect the valves visually for leakage.

  2. Run the script: D02 - Test System Tightness (What Should Be Tested = Sampler). This script also tests the column switching valves for leakage.

  1. If leakage still occurs, replace the Vanquish valve or the VICI valve stator and/or rotor seal depending on the valve.

    For the Vanquish valve, see Replacing the Vanquish Switching Valve.

    For the VICI valve stator and/or rotor seal, see Replacing the VICI Switching Valve Stator and/or Rotor Seal.
