Nov 10, 2022 · This article is a troubleshooting guide for when the Flame Ionization Detector (FID) does not ignite or the flame keeps going out. Cause: If the FID is having ignition issues, it is due to the following causes: FID temperature: is too low. Lit Offset: is incorrect.

• The FID is a DESTRUCTIVE, mass sensing detector • Cations generated in the flame are counted and produce the detector signal • Analytes that have the greatest number of low oxidation state carbons produce the LARGEST signal • The FID will respond to ORGANIC compounds (C-H Bonds) • There is little or NO response for the following:

Make sure that there is no visible dirt inside on the walls of the FID inlet (tube). Clean with wire (cleaning wire from Agilent or a thin .010 clean guitar string) and blow out gently with compressed air.

Inlet: Split (250°C) Detector: FID(320°C) Carrier Gas: Hydrogen Flow:37.3 cm/sec (1.8 ml/min) Holdup Compound: Methane (0.671-min) Temperature Program: Isothermal at 110°C Test Mix Used to determine how “good” the column is or if the …

The FID is a relatively simple detector in that if the electronics are functioning, a sudden change in performance is often either a matter of checking flows and cleaning or replacing the jet.

Jun 2, 2017 · Our 6890 GC-FID is refusing to light and stay lit. After inspecting the jet (clean) and the detector stack (also clean) I cleaned them anyway by sonication in methanol and acetone. After drying and reassembly.
