Preparing the Pump for Operation

Before Operating the Pump for the First Time
Before Starting Sample Analysis
Vanquish Pumps (VH-P10) Operating Manual
This section gives information on any additional steps that are required
to prepare the pump for operation and sample analysis.
Prepare the pump for the first-time operation, observing the following:
NOTICE Flush the system flow path thoroughly before operating the
pump for the first time:
•
When you install devices or components to the system, always flush
them to waste before connecting them in the system flow path. To
flush the Vanquish modules, follow the instructions in the Vanquish
System Operating Manual.
•
Some components of the pump are filled with isopropanol when the
pump is shipped from the manufacturing site. When operating the
pump for the first time, use solvents that are miscible with
isopropanol. If they are not, use an appropriate intermediate
solvent.
•
To remove the isopropanol from the pump components:
♦
Verify that the flow cell and the column are not connected in the
flow path.
♦
Purge the pump and then have the pump deliver flow for a short
time.
•
Verify that any air bubbles are completely flushed out of the system
flow path.
Before starting an analysis:
•
Check the liquid level in the solvent reservoirs. Verify that the
amount of solvent is sufficient for the analysis.
•
Verify that the doors of the modules in the Vanquish system are
closed.
