Atomic Absorption Spectroscopy
Atomic Absorption Spectroscopy (AAS) is a technique used to measure the concentration of metals in a sample. It works by shining light at specific wavelengths through the sample, which contains free atoms of the metal. If the metal is present, it absorbs some of the light, and the amount of light absorbed indicates the concentration of the metal. AAS is widely used in fields like environmental testing, food safety, and clinical analysis to ensure that materials meet safety standards by detecting trace levels of hazardous metals.

Atomic absorption spectroscopy (AAS) is an analytical technique used to determine the concentration of specific elements in a sample. It works by using light to measure how much light is absorbed by atoms in a vapor. A sample is atomized, typically using heat, and then a specific wavelength of light is directed through it. Each element absorbs light at unique wavelengths, allowing scientists to identify and quantify them. AAS is commonly used in environmental monitoring, food safety, and clinical analysis to detect metals and other elements in various substances.
