  "id": "MLC-T-CHM-008269",
  "term": "Optical emission spectroscopy",
  "field": "Chemistry",
  "definition": "An analytical technique that measures the intensity of light emitted by excited atoms or ions in a sample to determine its elemental composition. The sample is typically energized by a plasma, arc, or spark, causing atoms to emit light at characteristic wavelengths. This method is widely used for quantitative and qualitative elemental analysis.",
