  "id": "MLC-T-CHM-011156",
  "term": "Spectrochemical carrier",
  "field": "Chemistry",
  "definition": "A substance added to a sample for arc or spark emission analysis that produces a gas or vapour, which sweeps the vapourised sample into the zone where it is excited. Carbon is a standard example, because in an air atmosphere it forms carbon dioxide. In carrier distillation a compound such as gallium oxide is mixed in, and its vapour carries trace elements into the discharge.",
