This section provides information for best performance of the device
and gives hints on what you can do to optimize the performance further.
To optimize the performance of the device, consider the following
general guidelines:
• Monitor the usage of specific device components that are subject to
wear and stress and schedule appropriate maintenance intervals
(see Predictive Performance
• Observe the general guidelines and recommendations on the use of
solvents and additives in the chromatography system (see
Solvents and Additives
• Pumps with built-in vacuum degasser: Always use the built-in
vacuum degasser.
• Purge the pump when changing to a different type of solvent or
when restarting the pump after periods of inactivity.
TIP Shut off valves for solvent lines are available as an option (see
Installing Solvent Shut Off Valves
to shut off the solvent flow through the system at the solvent reservoir,
for example, to prevent solvent from flowing through the system when
the pump flow is zero for a longer period.
To shut off the solvent flow through the system at the solvent reservoir,
for example, to prevent solvent from flowing through the system when
you open a flow connection on the low-pressure side
The steps in this section apply only when installing a shut off valve after
initial operation of the pump. To install a shut off valve during initial
setup of the flow connections, follow the steps in
Solvent Lines (} page 64).
