When changing solvents.
After using buffer solutions to eliminate salt residues.
Before turning off, if you do not plan to restart the device within
shortly.
The installation has been completed.
The capillaries and hoses have been connected.
The pump has been switched on and is in „flow mode“.

Note:
If a buffer solution is used, select a solvent for purging in which the
buffer solution is soluble.
