WebDetectors Flame Ionization Detector (FID) Ions produced by combustion are collected at a pair of polarized electrodes to give a signal (increase in current). This current is amplified and recorded. The ionization efficiency is low but sufficient enough to give excellent sensitivity and linearity. WebFlame ionization detector. FID is a detector typically used with GC where the gaseous eluent is burnt in a flame, producing gas-phase ions of the analytes that are detected … regus iceland
