  "term": "Sequential spectrometer",
  "field": "Chemistry",
  "definition": "An instrument that measures the intensity of radiation at a series of different wavelengths or frequencies one after another in a timed sequence. A single detector is used, and the dispersing element, such as a grating or prism, is rotated or moved to present each wavelength to the detector's exit slit. This design contrasts with a simultaneous spectrometer, which uses multiple detectors to measure many wavelengths at once.",
