7697A Headspace Sampler Vial PCM Fault, Vial Flow Limited and External device not Ready

Hello Aleksandra,

Unfortunately provided information is not sufficient to give any further advice.
I would recommend you to contact your local distributor of Agilent, if this is not the case for you then start with this manual Agilent 7697A Headspace Sampler Installation and First Startup.

https://www.agilent.com/Library/usermanuals/Public/G4556-90013.pdf

There are several option how to connect a transfer line with 7820.
On the page 9 of this manual you will find the Table 3 Supported headspace sampler–GC connections and control modes.
From your errors it seems that you either have a big leak in the system or you have wrong connections of gases.
Can you leave some picture of your hardware setup? For example connection of the tube from Headspace Sampler to GC system? And other conenctions as well.

Those are the images of my setup.

I wouldn't blame the gas connection as it was working before. Unfortunately my coworkers who used to set this up are unavalible.

So are those vials errors are connected to flow patch? Maybe I should try to connect it again?

Have you managed to solve this issue?  
I would check for leaks in two directionts: 

1) From the source of gases to the GC and HSS.
2) From six port valve to Inlet

Another inportant point is the connection of your column to the inlet and detector.

From the picture you sent, I've noticed a valve, which probably used to swithc from ALS to HSS.

I had a service technician visit and he managed to solve this issue. It turned out that the inner capilar from HS to GC was broken near thesix port valve.

You are correct about the valve. It was in correct position during my trials.

Thank you for the advice!
