Atomic spectroscopy is a field that studies the interaction between light and matter in order to determine the properties of atoms and molecules. Synonyms for atomic spectroscopy include atomic emission spectroscopy, atomic absorption spectroscopy, and atomic fluorescence spectroscopy, all of which refer to specific techniques used to analyze samples. These techniques can be used to identify the presence and concentration of elements in a wide range of samples, including food, environmental samples, and clinical specimens. Atomic spectroscopy has many applications and is often used in fields such as environmental monitoring, pharmaceutical research, and material science. Regardless of the specific technique used, the goal of atomic spectroscopy is to provide accurate, precise, and reliable data to help answer important research questions.
