Description
Optical emission spectrometry involves applying energy in the form of spark generated between an electrode and a metal sample, whereby the vaporized atoms are brought to a high energy state. These excited atoms and ions in the discharge plasma create a unique emission spectrum specific to each element. Thus, a single element generates numerous characteristic emission spectral lines. By measuring the intensity of the peaks in this spectrum, analyzers can produce qualitative and quantitative metal analysis of the material composition with uncompromising accuracy.
