Optical emission spectroscopy (OES):

In the optical emission spectroscopy (OES) technology, atoms in a sample are excited by energy that comes from a spark formed between sample and electrode.

The energy of the spark causes the electrons in the sample to emit light which is converted into a spectral pattern. By measuring the intensity of the peaks in this spectrum, OES analysers identify the quality and quantity of the material composition with uncompromising accuracy. They are ideal for high performance analysis of alloyed and trace elements, nitrogen analysis in duplex steels.
