I have 8860 GC with cool on-column inlet. I replaced column with new ferrule in. I also replaced septa in the inlet. When I did "Leak and Restriction Test" using the software diagnostics, it shows restriction in primary sample flow path (inlet, column). .So I took column out, and clipped it, replaced ferrule and put it back again. Replaced septa as well. Confirmed no leak using leak detector. After that I tried "Leak &Restriction Test", it shows restriction again. Looking to see if anyone in the community has seen similar issue and were able to resolve it.
