Atmospheric pressure photoionization

{
  "id": "MLC-T-CHM-012899",
  "term": "Atmospheric pressure photoionization",
  "field": "Chemistry",
  "definition": "An ionization technique used in mass spectrometry where analytes are ionized by photons at atmospheric pressure. Ultraviolet light sources, such as a krypton discharge lamp, typically generate the photons. This method is suitable for nonpolar and moderately polar compounds that are difficult to ionize by electrospray.",
