The description below assumes that the Vanquish system is set up as
described in the System Operating Manual.
1. Turn on the system (refer to the Vanquish System Operating
Manual).
2. If applicable, disconnect the autosampler inlet capillary from the
pump/static mixer outlet port.
3. Connect the waste line to the pump/static mixer outlet port.
4. Insert the other end of the waste line into the waste container.
5. Start the pump flow at the maximum flow rate of your application.
6. Check all flow connections for leakages:
If a leakage has occurred: See
¨
(} page 170).
If no leakage was found and the pressure value has stabilized:
¨
Proceed with the next step.
