Hi,
I recently cleaned a 7820 GC inlet and replaced all the replaceable parts. After starting the GC I realized that I have inlet leak. When I start the leak check total flow stays on ~3.4 while column flow is ~1.3. I checked all inlet parts, reopened and closed them, but still the flows remain the same. It doesn't even increase, let alone decrease.
Any help would be really appreciated!
