ATOMIC ABSORPTION SPECTROSCOPY

INTRODUCTION
Atomic absorption (AA) spectroscopy is an analytical method that supports qualification and/or quantification of elements. In this use, the AA method supports procedures that measure the absorbance of radiation at a characteristic wavelength by a vapor composed of ground state atoms. A typical instrument consists of a primary energy source that produces the spectrum of the element under examination, a monochromator, and a suitable detector.
For discussion of the theory and principles of measurements, see Atomic Absorption Spectroscopy—Theory and Practice 〈1852〉, a resource that may be helpful but is not mandatory.
