Atomic absorption spectroscopy - Wikipedia
Atomic absorption spectroscopy (AAS) is an elemental analysis method for determining the concentration of metals in a given sample. [1] The principle of AAS relies on the vaporization of metals within a sample when introduced to a flame. Every ground state metal absorbs light radiation (and excites) at a different wavelength.
Atomic Absorption Spectrophotometry: Principle, Parts, Uses
Atomic absorption spectrophotometry is a widely used analytical technique that involves the measurement of the absorption of electromagnetic radiation by atoms in the gas phase.
