  "term": "Interlaboratory comparison",
  "field": "Chemistry",
  "definition": "An organized program where multiple laboratories analyze identical samples and compare their results to assess measurement proficiency and data comparability. This process evaluates the performance of analytical methods and laboratories against a common reference. It is a key component of quality assurance in analytical chemistry.",
