  "id": "MLC-T-CHM-008873",
  "term": "Photographic plate recording",
  "field": "Chemistry",
  "definition": "A method of detecting and recording ions in mass spectrometry by exposing a photographic emulsion to the ion beam. The ions cause chemical changes in the emulsion, which, after development, produce darkened lines or spots corresponding to their mass-to-charge ratios. This technique provides a permanent, integrated record of the mass spectrum.",
