Abstract

In this investigation we compared the analytical results obtained by inductively coupled plasma optical emission spectroscopy (ICP-OES) and a scanning electron microscope with an energy dispersive X-ray analysis system (SEM-EDX). The powder and dust, obtained by laser-processing of CRN-14301 steel, was analysed to classify the powder and dust for its final waste disposal. For this reason we analysed the elemental content of the samples. The samples consisted of a mixture of metals and their oxides.

The solid powder and dust was analysed directly by SEM-EDX, the ICP-OES analysis was carried out after the solid was dissolved in an acid solution. Both analytical methods were in good agreement.

ICP-OES showed a higher precision and lower detection limit than EDX, but SEM-EDX showed a higher amount of information regarding the sample composition.
