FID unstable flame

obedboakye

My FID flame lights for 2 min and the hydrogen and air flows fluctuates afterwards leading to quenching of the flame. Any ideas please ?

    Hi obedboakye

    , What your GC modal? the pressure good for FID

    •  Try to test flow for FID by flow  meter is wetuski suggestion we faced same problem and after we checked FID flow gases we discover different      between GC air flow (350 ml/min) display and the real value (100ml/min) from flow meter and this  confirm the EPC for zero  air damage because.... high moisture in zero air
