Pressure of inlet not reaching set point

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 will go through and do the leak checks next time, but I am interested in anyone’s opinions and experiences in the meantime.


Many thanks.
