Hi all,
The 7890B GC shows Back detector fault. The FID is reading 5.6 E06 pA.
The GC is installed within a glove box and access is limited and maintenance cannot be performed.
Any ideas? I had recently also a failure on a trace heating controller (trace heating installed on a custom made FID chimney) and i think it might be electrical issue.
Thank you,
Giannis
