  "id": "MLC-T-CHM-003798",
  "term": "Electrothermal atomic absorption spectroscopy",
  "field": "Chemistry",
  "definition": "An analytical technique for determining the concentration of trace elements in a sample by atomizing the sample in an electrically heated graphite furnace. The atoms then absorb light at specific wavelengths from a hollow cathode lamp, and the decrease in light intensity is measured. This method offers high sensitivity for many elements, with detection limits often in the picogram range.",
