  "term": "Corona discharge",
  "field": "Chemistry",
  "definition": "A localized electrical discharge that occurs in a fluid, such as air, around a conductor when the electric field strength exceeds a certain threshold but is insufficient to cause a complete breakdown or spark. It is characterized by a faint glow and the production of ions and ozone. In analytical chemistry, it is used in some ionization sources for mass spectrometry.",
