Inner filter effect

  "id": "MLC-T-CHM-005881",
  "term": "Inner filter effect",
  "field": "Chemistry",
  "definition": "The attenuation of incident or emitted light in a spectroscopic experiment due to absorption by the sample itself or other components in the solution. This phenomenon can lead to a non-linear relationship between analyte concentration and measured signal intensity. It is particularly relevant in fluorescence spectroscopy, where both excitation and emission light can be absorbed.",
