ATOMIC EMISSION SPECTROSCOPY

Atomic Emission Spectroscopy

- Is an analytical technique used to determine the identity, the structure and the environment of atoms by analyzing the radiation emitted by them.
- By analyzing the radiation emitted by its atoms when they are excited. The emitted light has characteristic wavelengths and analyte concentrations can be estimated by evaluating the light absorptive and emissive properties of the sample

- Is an analytical technique used to identify and quantify elements in a sample based on the light emitted by excited atoms.
- The sample is first vaporized and then excited using an energy source such as a flame or plasma.
- This excitation causes the atoms to emit light at specific wavelengths characteristic of each element.

Spectrometer

Main Principle of AES
Detects and analyzes this emitted light, and because the intensity of each wavelength is directly proportional to the concentration of the corresponding element, the resulting spectrum allows for both the identification and quantification of the elements present in the sample.

RESERACH RELATED
-Is favored for its high sensitivity and multielement detection capabilities
- It uses a high-energy plasma, typically generated from an inert gas like argon, to excite atoms, which then emit light at specific wavelengths, allowing for the identification and quantification of elements.
