I am attempting to troubleshoot a leak on an Agilent 1260 G1312B binary pump. I cannot see any leaks, but my I know there is one because my leak test (pressure test) is failing with the blanking nut set at the purge valve.
Parts i replaced:
-Outlet ball valve
Before and after replacing the outlet ball valve, I am getting inconsistent results when running the valve test through LabAdvisor. Sometimes it will say the ball valve is defective or the AIV results are ambiguous. Other times they will pass.
Looking for suggestions on troubleshooting this leak I cannot solve.
