Spark ionization

  "id": "MLC-T-CHM-011076",
  "term": "Spark ionization",
  "field": "Chemistry",
  "definition": "An ionization technique used in mass spectrometry where a high-voltage spark is discharged between two electrodes, one of which contains the sample. The intense energy from the spark vaporizes and ionizes a small portion of the sample, producing a plasma of ions. These ions are then extracted and analyzed by a mass spectrometer, typically for elemental analysis of solid materials.",
