Air Flow Shutting Down

Good day . i have another issue to my 8890. after replacing the fused silica in transfer line. tha air flow in FID is suddenly shutting down. then i try the detector diagnostic in the system it said test failed and need to replace the jet.

after replacing the jet the air flow is still shuting down with hydrogen while igniting.

  • Hi sir this is my set point

    air flow = 400ml/min

    Fuel Flow = 55ml/min

    Makeup (N2) = 5ml/min.

    yesterday its already ignited and the flame its on. 

    we already run asequence many times. 

    today when we run again the PCM A shutting down before end the sample running. 

    our pcm flow is 69ml/min 

    and now its hard to ignite again. 

    thank you for your quick response
