WebFlame-ionization detector (FID) has a nearly universal response to organic compounds, a low LOD and a wide linear response range (10 7 ). The FID response results from the … WebFlame Ionization Detector (FID) Supplies. Flame ionization detection is the most commonly used GC detection method due to it's superior ability to measure hydrocarbons. Using a carrier gas, the sample is ionized via a hydrogen-air flame, then collected using a polarizing voltage. The current produced is measured and used to quantify the amount ...
