  "id": "MLC-T-CHM-003041",
  "term": "Depth resolution parameter",
  "field": "Chemistry",
  "definition": "A quantitative measure of the sharpness of an interface observed in a depth profile, often expressed as the distance over which the signal intensity changes from 16% to 84% of its maximum value. This parameter reflects the ability of a surface analysis technique to resolve compositional changes with depth. A smaller value indicates better depth resolution.",
