  "id": "MLC-T-CHM-008570",
  "term": "Peak matching",
  "field": "Chemistry",
  "definition": "A technique in mass spectrometry where the exact mass of an unknown ion is determined by comparing its mass-to-charge ratio with that of a known reference ion. Both ions are measured simultaneously or in rapid succession under identical conditions. This method provides highly accurate mass measurements, often to within a few parts per million.",
