Fluidics error in console of Vion in UNIFI
- Vion IMS QTof
Leak sensor triggered due to leak at fluidics.
FIX or WORKAROUND
Purge sample fluidics.
Inspect the leak sensor under the divert valve (where LC is connected to Vion).
If you find liquid at the leak sensor under the divert valve, dry the leak sensor.
Purge the sample fluidics. Error should disappear.
Troubleshooting for leak at divert valve. Either peek tubing or sample probe capillary.
- Put flow on LC and confirm the pressure read back.
- Remove the black PEEK tubing from the sample probe capillary. (If there is a large pressure drop, the probe is blocked.)
- Remove the black PEEK tubing from the divert valve. Use paper for the excessive liquid from the LC. (If there is a large pressure drop, the black PEEK tubing is blocked.)
- Replace the blocked portion and inspect the pressure with LC flow.
