Hydrocarbon selective Robust, linear, stable Detects down to 1ppm Unique ceramic ignitor can run hot continuously to keep flame lit
The flame ionization detector is the most commonly used GC detector, responding linearly from its minimum detectable quantity of about 100 picograms to almost 100%.

The FID responds to any molecule with a carbon-hydrogen bond, but not at all, or poorly, to compounds such as H₂S, CCl₄ or NH₃. The FID response is very stable from day to day, and is not susceptible to contamination from dirty samples or column bleed.

The chromatogram above shows 250 ppm C₁-C₆ hydrocarbons (methane through hexane) standard as detected by the FID. CO₂, also at 250 ppm, is converted to methane by the Methanizer accessory in the jet of the FID detector.

Our FID employs a unique ceramic ignitor which can run hot continuously, immediately re-igniting the flame even when presented with large water injections or pressure surges from column backflush.
