  "term": "Proton-Transfer-Reaction Mass Spectrometry",
  "field": "Environment",
  "definition": "1. Method of determining concentration of a component in a gas mixture by attaching to it a proton, the resulting product then being measured by any convenient means of mass spectroscopy.\n\n2. Type of mass spectrometry in which H3O+ ions are made to interact with trace amounts of substances of interest to form charged ions (by proton transfer) which are then analyzed by a mass spectrometer.",
