  "term": "Flame ionization detection",
  "field": "Meteorology and atmospheric science",
  "definition": "A common analytical technique used in gas chromatography to detect organic compounds. It operates by burning the effluent from a gas chromatograph in a hydrogen-air flame, which ionizes carbon-containing molecules. The resulting ions are then collected, producing an electrical current proportional to the concentration of the organic compound, making it highly sensitive to hydrocarbons.",
