  "term": "Appearance temperature",
  "field": "Chemistry",
  "definition": "The minimum temperature at which a specific analyte signal can be detected in electrothermal atomic absorption spectrometry. This temperature is determined by heating the sample in a graphite furnace and observing the onset of the atomic absorption signal. It is influenced by the matrix composition and the chemical form of the analyte.",
