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 Use of 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). These valves allow you 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.
