Maintaining The Leak Sensor - Waters ACQUITY UPLC Operator's, Overview And Maintenance Manual

Maintaining the leak sensor

A leak sensor in the drip tray continuously monitors the detector for leaks.
The sensor stops system flow when it detects accumulated, leaked liquid in its
surrounding reservoir, and an error message describing the problem appears
in the ACQUITY UPLC Console.
Resolving detector leak sensor errors
After approximately 1.5 mL of liquid accumulates in the leak sensor reservoir,
an alarm sounds, indicating that the leak sensor detected a leak.
Warning:
with biohazardous and/or toxic materials. Always wear clean,
chemical-resistant, powder-free gloves when performing this
procedure.
Caution:
• do not allow buffered solvents to accumulate and dry on it.
• do not submerge it in a cleaning bath.
Required materials
• Clean, chemical-resistant, powder-free gloves
• Cotton swabs
• Nonabrasive, lint-free wipes
To resolve a detector leak sensor error
1. View the Leak Sensors dialog box in the ACQUITY UPLC Console to
verify that the leak sensor detected a leak.
If a leak is detected, a "Leak Detected" error message appears.
Tip:
2. Open the detector door, gently pulling its right-hand edge toward you.
3. Locate the source of the leak, and make the repairs necessary to stop the
leak.
The leak sensor and its reservoir can be contaminated
