Atomic Absorption Spectrophotometer

An Atomic Absorption Spectrophotometer (AAS) is an analytical instrument used to measure the concentration of specific metals or elements in a sample. It works by converting the sample into free atoms in a gaseous state, then shining a light at a wavelength absorbed by the target element. The amount of light absorbed indicates how much of that element is present. AAS is highly sensitive and precise, making it useful in fields like environmental testing, clinical analysis, and food safety to detect trace levels of metals or minerals accurately.
