  "id": "MLC-T-CHM-004469",
  "term": "Flame photometric detector",
  "field": "Chemistry",
  "definition": "A selective detector used in gas chromatography for compounds containing sulfur or phosphorus. The effluent from the gas chromatograph is introduced into a hydrogen-rich flame, causing these elements to emit light at characteristic wavelengths. A photomultiplier tube measures the intensity of this emitted light, typically at 394 nm for sulfur and 526 nm for phosphorus.",
