  "id": "MLC-T-CHM-009008",
  "term": "Plasma desorption ionization",
  "field": "Chemistry",
  "definition": "A soft ionization technique used in mass spectrometry where ions are produced from a solid sample by bombarding it with energetic fission fragments from a radioactive source, typically californium-252. This method is suitable for analyzing large, thermally labile biomolecules. It generates intact molecular ions with minimal fragmentation.",
