How do you prepare an ACQUITY UPLC for long-term storage? - WKB232868

ANSWER
To shut down the system for more than 24 hours:
1. To lengthen lamp life, extinguish the detector lamp by clicking (Lamp Off) in the detector control panel.
2. Remove buffer salts and additives by flushing with water.
3. Flush the system, column, and flow cell with 100% organic solvent (for example methanol or IPA). See also: Waters Column Care and Use Instructions
4. Power-off the system. Alternative: If you prefer to leave the system powered-on, turn off the column heater or reduce the column heater temperature to 40 °C (104 °F).
5. Cap the flow cell inlet and outlet ports.
Warning: Risk of electric shock. The power switch on each system instrument controls the basic operational state of that instrument. Nevertheless, some instrument circuits remain live after the instrument is switched off. To completely interrupt power to a system instrument, set the power switch to Off, and then unplug the instrument’s power cord from the AC outlet.
Caution: Before using any system or instruments that have been shut down under the recommended conditions, ensure that the new mobile phase is miscible with the recommended storage solvents (water/methanol or water/acetonitrile). If the mobile phase and solvents for the new analysis are not directly miscible with the recommended storage solvents, ensure that an intermediate solvent, one that is miscible with both the storage solvents and those for the new analysis, is used to flush the storage solvents from the system and all of its components.
