  1. 6890 GC Detectors - The Flame Ionization Detector

  2. 6890 GC Detectors - The Flame Ionization Detector - Main Components Igniter Teflon Insulator Collector Interconnect/Spring Electrometer Jet Heater/Sensor Assembly Detector Base Assembly Column Adapter

  3. 6890 GC Detectors - The Flame Ionization Detector

  4. 6890 GC Detectors - The Flame Ionization Detector - Theory of Operation 1. H2 - Air Flame 2. Sample is burned in flame 3. When burned produces charged Ions 4. Ions attracted to collector 5. Collector current converted to output via Electrometer

  16. 6890 GC Detectors - The Flame Ionization Detector

  17. 6890 GC Detectors - The Flame Ionization Detector Flame won't light Measure Flows Clean/Replace Jet (6850 Jet Test) Are column and fittings tight ? Is the tank pressure high enough ? Is the Detector ON ?

  18. 6890 GC Detectors - The Flame Ionization Detector Noisy Baseline Turn off Air/H2 No Contamination Still Noisy problem Yes Electronic/Mechanical Problem Check: Filters,Traps,Gasses Clean Jet Replace Detector Verify Column max Board/ interconnect/ Teflon Insulators

  19. HP 6890 - Flame Ionization Detector Planned Maintenance - Replace Jet (per Customer) - Clean/Replace Collector - Inspect interconnect and spring - Inspect ignitor glo-plug - replace if necessary - Measure H2/Air/Makeup Flows - Turn off H2 and measure FID Leakage Current - < 2pA - Ignite FID - monitor background and noise <20 pA and stable - Run customer sample or Agilent Checkout per 6890 Service Manual section 600.
