spectrometer
/spek'trɔmitə/
Definition
- 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.
