Not Ready

The LED display on the front of the GC says "Status Ready" but on the monitor it says "Not Ready" in the yellow bar.  If I try to run a sequence it turns blue "Sequence Running" for a few seconds then yellow "Sequence Stopping".  I have a 7820A GC running off Chemstation software.

  • first try an other method 

    if it works normally check your parameters, maybe injection source is manual not ALS

    also monitor your gases and pressures and make sure thar the flame is ON

    sometimes the inlet can'treach the pressure

    or the makeup flow is too high

    ...

    if you see that every thing is OK try to create a new method
