Solute-volatilization interference

  "id": "MLC-T-CHM-011013",
  "term": "Solute-volatilization interference",
  "field": "Chemistry",
  "definition": "An interference in flame atomic spectrometry in which a concomitant substance changes how fast the dry aerosol particles volatilize, so that the analyte is released incompletely and fewer free atoms form. A classic case is phosphate lowering the calcium signal in an air-acetylene flame because a thermally stable calcium phosphate forms. Adding a releaser such as lanthanum, which combines preferentially with the interferent, reduces it.",
