Is a spectrometer a mandatory detection instrument
Spectrometers are used in astronomy to analyze the chemical composition of stars and planets, and spectrometers gather data on the origin of the universe. Examples of spectrometers are devices that separate particles, atoms, and molecules by their mass, momentum, or energy.OverviewA spectrometer is a scientific instrument used to separate and measure components of a physical phenomenon. (often simply called "spectrometers"), in particular, show the intensity of as a function of wavelength or of frequency. The different wavelengths of light are separated by in a or by. Generally, the of an instrument tells us how well two close-lying energies (or wavelengths, or frequencies, or masses) can be resolved. Generally, for an instrument with mechanical slits, higher resolution.
