Use this function if you see excessive pressure or composition ripple, and you are sure that the solvent type (aqueous/organic or specific solvent/solvent mix) is correctly set, and there is no evidence of leakage in the pump. Conditioning may be necessary if the pump may contain air, for example after running out of solvent, after a long period of standby or after service or repair.
Condition the pump with a restriction that provides at least 200 bar (> 500 bar is better). You may run conditioning with the normal load, such as the column under the conditions of the analysis.
The conditioning process should decrease the ripple over time (for example, half an hour); if the ripple remains unchanged and higher than about 10% of the pressure, contact your service representative.
