Flame Ionization Detector
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 Flame Ionization Detector responds to any molecule with a carbon-hydrogen bond, but not at all, or poorly, to compounds such as H2S, CCl4 or NH3. The Flame Ionization Detector response is very stable from day to day. Our Flame Ionization Detector 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.
