7697A leak test failed


Our Headspace sampler 7697A Leak test failed. Leak test failing at the stage 1 off the Restriction and Pressure Decay Test.

Going from there, the sample probe was replaced as well as the pressurization solenoid valve but without success.   

The method for the 7697A was set up as continue in case of “vial leak test fails” and the chromatograms of our samples did not seem to have problem.

All vials are marked as leaking in the Activity log, sometimes with leak over 50mL/min.   

Do we have really a leak or is something else happening like failing PCM module?   

Thanks for your help.
