On the other hand, spectrometry is the method used to acquire a quantitative measurement of the spectrum. In short, spectroscopy is the theoretical science , and spectrometry is the practical measurement in the balancing of matter in atomic and molecular levels.
This could be a mass-to-charge ratio spectrum in a mass spectrometer, the variation of nuclear resonant frequencies in a nuclear magnetic resonance NMR spectrometer, or the change in the absorption and emission of light with wavelength in an optical spectrometer. The mass spectrometer, NMR spectrometer and the optical spectrometer are the three most common types of spectrometers found in research labs around the world.
A spectrometer measures the wavelength and frequency of light, and allows us to identify and analyse the atoms in a sample we place within it. In their simplest form, spectrometers act like a sophisticated form of diffraction, somewhat akin to the play of light that occurs when white light hits the tiny pits of a DVD or other compact disk. Light is passed from a source which has been made incandescent through heating to a diffraction grating much like an artificial Fraunhofer line and onto a mirror.
As the light emitted by the original source is characteristic of its atomic composure, diffracting and mirroring first disperses, then reflects, the wavelength into a format that we can detect and quantify.
