Spectrometric analysis is a scientific technique used to identify and quantify substances based on their interaction with electromagnetic radiation. This method involves measuring the intensity of light absorbed, emitted, or scattered by a sample, which provides information about its chemical composition and structure. Common types of spectrometric analysis include mass spectrometry, infrared spectroscopy, and ultraviolet-visible spectroscopy. The data obtained from spectrometric analysis is often displayed as a spectrum, which is a graph showing the intensity of light at different wavelengths. By analyzing these spectra, scientists can determine the presence of specific compounds, their concentrations, and even their molecular characteristics, making this technique essential in fields like chemistry, biology, and environmental science.
