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
The differential absorption of wavelengths by individual elements is determined by measuring their absorbance against established standards. The Atomic Absorption Spectroscopy technique takes advantage of the distinct radiation wavelengths that are selectively absorbed by individual atoms.
What Is Atomic Absorption and How Does It Work?
Atomic Absorption (AA) is a highly specific analytical technique used to determine the concentration of metallic elements within a sample. The method relies on the principle that atoms absorb light at unique and precise wavelengths.
1.4: Introduction to Atomic Absorption Spectroscopy
Atomic emission spectroscopy measures the intensity of light emitted by the excited atoms, while atomic absorption spectroscopy measures the light absorbed by atomic absorption. This light is typically in the visible or ultraviolet region of the electromagnetic spectrum.
