6890N I am having an issue with GC Not Ready Front Inlet Pressure Not Ready. The pressure overshoots by about 0.5 psi in both directions and won't stabilize. The autosampler won't make the injection because of the not ready condition.
Column 30 m x 0.25mm x 250 um. 1 mL/min Split 20:1 Constant Flow Pressure 18.4 (goes back and forth between 17.9 psi and 19.0 psi) Total Flow 20.1 Could it be ECP? I haven't had issues before.
