Pure-element relative sensitivity factor

  "id": "MLC-T-CHM-009683",
  "term": "Pure-element relative sensitivity factor",
  "field": "Chemistry",
  "definition": "A quantitative parameter used in surface analysis techniques, such as X-ray photoelectron spectroscopy (XPS), that relates the measured signal intensity of an element to its concentration in a pure, unadulterated sample. This factor accounts for differences in ionization cross-sections, detector efficiencies, and other instrumental parameters for each element. It serves as a baseline for calculating elemental concentrations in complex matrices.",
