  "term": "Chemiluminescent methods of detection",
  "field": "Chemistry",
  "definition": "Analytical techniques that rely on the emission of light from a chemical reaction to detect and quantify specific substances. The analyte reacts with a reagent to produce an excited state intermediate, which then decays to a lower energy state by emitting photons. The intensity of the emitted light is proportional to the concentration of the analyte, often measured by a photomultiplier tube.",
