7697A leak test failed

Hi GOLF,

Did the restriction test failed after changed  sample probe? if it passed, you can switch off the HS, press clear at HS keypad, hold pressing clear for 5 seconds meanwhile  switch on the HS  and continue 5sec pressing clear. Hope it works

Hi FCA,

Thanks, for your input.

Restriction is still there. The Cross Port Leak Test  is passing, I believe the six port valve is not in cause. And Chromatograms are still good. But The HS has to be set up as If Leak test failing Continue . 

Hello GOLF ,

If you have not done that already, I would suggest going through the leak and restriction manual, as it gives you a visual of what is being tested at each step. Sounds to me like page 11 is the part where your test is failing at. So, the sample probe, SV1, 6-port or the PCM could be a reason for it.  

Hi CMZainea,

Thank you for your feedback. The leak test for the 6 ports valve was passing, so no leaks detected at the valve. Any other leaks were detected from the visible piping and connection from the back panel of the 7697A going to the 6 ways valve.

That just leave the PCM module ($$$$) or the pressurization valve. Or something else.

So far the system is running with the feature "vial leak test off" and it the seems to have a leak. But if placed back on each injection will fail as vial leak detected.

Golf.
