  • HI Sebastien, 

    What are your detector flow outputs and what are the current readings?  If the readings are low, do you have enough pressure to supply the GC?  You could also have a plugged jet.  


  • For the GC-6890 FID detector issues you're experiencing, here's a simplified approach to troubleshoot the errors:
    1. Gas Supplies:

      • Make sure all gas supplies (utility, makeup, hydrogen) are on.
      • Check that the pressure and flow rates are correct.
    2. Gas Lines and Connections:

      • Look for any leaks in the gas lines and fix them.
      • Ensure connections are secure and there are no blockages.
    3. Detector Settings:

      • Double-check the front detector settings on the GC-Control Panel to make sure they're correct.

    Remember to always follow safety guidelines when working with the GC.
