  "id": "MLC-T-CHM-003803",
  "term": "Elemental relative sensitivity factor",
  "field": "Chemistry",
  "definition": "A proportionality constant that relates the measured signal intensity of a specific element to its actual concentration in a sample, relative to a reference element. This factor accounts for differences in ionization efficiency, detection efficiency, and matrix effects between elements. It is used in quantitative surface analysis techniques like secondary ion mass spectrometry.",
