The split vent line has recently been cleaned on our GC (7890B model) and I believe since then the inlet pressure has been unable to reach set point (pressure is below 1psi – a major leakage!). I was wondering if an improperly installed split vent line can cause such problems?
We use split mode in our GC operations.
I tried re-tightening the fittings on the split vent line and in the inlet area and still no change. I will do a thorough leak check next time, but I am interested in anyone’s opinions and experiences in the meantime.
Many thanks.
