  "term": "Additional gases",
  "field": "Chemistry",
  "definition": "Gases introduced into a plasma or flame in atomic spectroscopy, besides the primary plasma or flame support gases. These gases are added to modify the plasma or flame characteristics, such as temperature or chemical environment, to affect the atomization or excitation processes of the analyte. Common examples include adding nitrogen to an argon plasma or hydrogen to an air-acetylene flame to reduce chemical interferences from oxides.",
