How to reset after a nitrogen gas failure on a Xevo MS - WKB5116

OBJECTIVE or GOAL

After nitrogen gas pressure into the mass spectrometer drops below 100 psi, the nitrogen supply stops or the supply tank or dewar is replaced, you must reestablish the pressure and reset the error message. 

ENVIRONMENT

• Xevo TQD
• ACQUITY TQD
• Xevo TQ-S micro
• Xevo G2-XS
• SQ Detector 2
• Xevo TQ-S
• Xevo TQ-XS
• Xevo TQ Absolute 

PROCEDURE

Ensure that nitrogen gas is being supplied at 100 psi to the back of the instrument before resetting the error message.

1. Go to the MS tune page.
2. Click on the Gas drop-down menu.
3. Select Reset Nitrogen Gas Failure.

The error message should now be gone, and operation can commence.

Note: You may also need to purge the Fluidics from the Fluidics tab on the tune page.
