Spark Spectroscopy analysis

First of all, spark spectrometry is an analytical device used to determine the chemical composition of a metal.

A spark is made between the sample and the tungsten electrode, which heats the atoms to a high temperature.

Then, the excited atoms emit light at a characteristic wavelength. Finally, this light is analyzed to determine the components of the metal.

Moreover, the analysis by spark spectrometry is particularly used in industry. Indeed, it allows to validate the conformity of a part according to a standard or a particular specification.
