Atomic Emission Spectroscopy

Aakshi Kainthola

 Atomic Emission Spectroscopy (AES) is a chemical analysis method that employs the intensity of light produced at a certain wavelength from a flame, plasma, arc, or spark to quantify the quantity of an element in a sample. The identification of the element is determined by the wavelength of the atomic spectral line in the emission spectrum, while the intensity of the emitted light is related to the number of atoms in the element. Various methods can be used to excite the sample. By examining the radiation released by atoms, atomic emission spectroscopy can be used to establish their identification, structure, and surroundings. We may determine the energy levels (or stationary states) of the atom from wavelength measurements, and this offers an experimental basis for atomic structure theories.
