Infinity III DAD – Pressure Relief Valve Leak Without Leak Alarm Triggering?
Infinity III DAD – Pressure Relief Valve Leak Without Leak Alarm Triggering?
-
However, when we checked the system the next morning, no obvious leak was visible. After re-priming and setting everything up again, we observed that leakage was occurring from the waste tubing connected to the DAD pressure relief valve.
Leak - Injector valve position 6 or column inlet, PEEK fittings

We believe a user accidentally increased the flow rate too high with the purge valve closed, which seems to have led to pressure build up and a fitting to pop off (at the injector valve position 6). We have cut the tubing and changed the fittings, but we are still seeing a leak at the switching valve or the column inlet.

Infinity 1290 LC-MS, diverter valve #5067-4241. Our diverter valve is leaking during sample runs. I replaced the rotor seal and all connected capillaries. I made sure that there are no obstructions in the valve head. The unit does not kick out any errors and chromatography looks fine. Also, no pressure issues. But the leak will cause a shut down if unchecked. All of the valve head bolts are tight. Please help before I buy a $4K new part.

Hi! I'm encountering ongoing leakage from the outlet valve despite replacing the cap assembly. This persists whenever I close the purge and start a run. Furthermore, when purging to remove bubbles, I'm still observing a significant amount of bubbling in the waste tube.
