  "id": "MLC-T-CHM-010856",
  "term": "Signal-to-noise ratio",
  "field": "Chemistry",
  "definition": "The ratio of the amplitude of a desired analytical signal to the amplitude of the background noise in a measurement. A higher ratio indicates a clearer signal and better measurement precision, allowing for the detection of lower analyte concentrations. This ratio is a fundamental metric for evaluating the performance of analytical instruments and methods.",
