    Agilent 6890 High Pressure/Low Flow - Shutoff error

    b_haas

      I am working with an Agilent 6890, Splitless Inlet, and am having problems with the pressure maxing out and cutting off flow. The Front Inlet Low Flow Shutoff notice shows and the GC stops running. I have checked the septum/septum nut, replaced the liner, checked the gold seal, and clipped the column, none of these things fixed the problem. We cannot run the instrument for more than 2-3 minutes before it shuts off.
