2.6 Priming the seal-wash system

Prime the seal wash in the solvent manager, to lubricate the plungers, fill the tubing paths with
solvent, and flush away solvent and any precipitated salts that have been dragged past the
plunger seals from the high-pressure side of the piston chambers.
Prime the seal-wash system,
• after using buffered mobile phase;
• when the solvent manager has been inactive for a few hours or longer;
• when the solvent manager is dry.
Notice:
do not use a nonvolatile buffer as the seal wash solvent.
Notice:
compatible with the mobile phase conditions.
Notice:
To avoid damaging the seats and seals of solenoid valves in the solvent path,
To avoid clogging system tubing, ensure that the seal-wash solvent is 100%
To avoid contaminating system components, do not recycle seal wash.
