Atomic spectroscopy is a technique used to study the interaction between electromagnetic radiation and matter. It is used to identify and quantify the elements present in a sample. Atomic absorption spectroscopy (AAS) is a type of atomic spectroscopy that measures the amount of light absorbed by the atoms in a sample

AAS is commonly used to determine the concentration of metals in a sample. The sample is atomized and then exposed to a beam of light. The light is absorbed by the atoms in the sample, and the amount of absorption is proportional to the concentration of the metal in the sample
