Dwell time

  "id": "MLC-T-CHM-003484",
  "term": "Dwell time",
  "field": "Chemistry",
  "definition": "The time interval between successive sampled data points in a digitised spectroscopic signal, or the time a scanning detector spends measuring at each point. In NMR it equals the reciprocal of the spectral width, so a spectral width of 10 kHz corresponds to a dwell time of 100 microseconds. In mass spectrometry it is the time spent monitoring one selected ion.",
