spectrometer

A scientist uses a spectrometer to analyze a sample.

Definition
  1. Noun:
    • An instrument used to measure properties of light over a specific portion of the electromagnetic spectrum: A spectrometer is a scientific device that separates and measures light or other radiation into its component wavelengths or energies to analyze the composition of a substance.
    • A device for obtaining a mass spectrum: In physics and chemistry, a spectrometer can specifically refer to an instrument that measures the mass-to-charge ratio of ions to determine the composition of a sample.
Usage Examples
  • Noun:
    • The astronomer used a spectrometer to analyze the light from the distant star.
    • The lab is equipped with a mass spectrometer for chemical analysis.
Advanced Usage
  • "to operate a spectrometer": to use or control the functions of a spectrometer.
    • Researchers must be trained to operate the spectrometer correctly.
  • "spectrometer data": the information or measurements obtained from using a spectrometer.
    • The spectrometer data revealed the presence of unknown elements.
Variants and Related Words
  • Spectrometry (n): The scientific technique or process of using a spectrometer.
    • Mass spectrometry is a common analytical method.
  • Spectroscopic (adj): Relating to or employing spectroscopy or a spectrometer.
    • The spectroscopic analysis was conclusive.
  • Spectroscope (n): An optical instrument for forming and examining spectra, often a simpler or more specific type than a full spectrometer.
Synonyms
  • Analytical instrument: A device used for detailed examination of substances.
  • Mass spectrograph: A specific type of spectrometer that records a mass spectrum photographically or digitally.
Related Phrases
  • Coupled with a spectrometer (phrase): Connected to or used in conjunction with a spectrometer.
