OverviewHistoryInstrumentationBackground absorption and background correctionApplicationsFurther reading

Atomic absorption spectroscopy (AAS) is an elemental analysis method for determining the concentration of metals in a given sample. 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. This uniqueness allows each metallic element to have its own
