Definitions for "Flame ionization detector"
A carbon detector that relies on the detection of ions formed when a carbon-containing material, such as a volatile or gaseous hydrocarbon, is burned in a hydrogen-rich flame. This detector is commonly used in a gas chromatograph to detect and quantitate organic compounds. It is also employed in some portable instruments.
A gas chromatography detector in which the column effluent gas is mixed with hydrogen and burned in air or oxygen. The ions and electrons produced in the flame produce an electric current proportional to the amount of material in the detector. The FID responds to nearly all organic compounds, but it does not respond to air and water, making it exceptionally suited to environmental analysis.
gas chromatographys detector based on measurement of ion current in a flame. Sensitive and rugged but destructive to sample.
