Atomic spectroscopy is a powerful analytical technique used to study the interaction of atoms with electromagnetic radiation. It allows for the identification and quantification of elements by measuring the absorption, emission, or fluorescence of light by atoms. Common types include atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES), and inductively coupled plasma mass spectrometry (ICP-MS). This technique is widely used in chemistry, environmental monitoring, and materials science for precise elemental analysis.
