  "id": "MLC-T-CHM-013103",
  "term": "Field desorption",
  "field": "Chemistry",
  "definition": "An ionization technique in mass spectrometry where a strong electric field is applied to a sample deposited on an emitter, causing molecules to desorb and ionize directly from the solid or liquid phase. This method is particularly useful for analyzing non-volatile, thermally labile, or high molecular weight compounds. It minimizes fragmentation, yielding predominantly molecular ions.",
