Laser Induced – Breakdown Spectroscopy for Quantitative Sn Analysis in Zr Based Alloys

Laser induced breakdown spectroscopy (LIBS) calibration curves for ZrSn alloys were obtained. Relationships between the atomic emission lines present in the spectra and the Sn concentration of the samples showed a linear behavior. Also Zy-2 standards were measured to contrast the behavior of the technique in different kind of alloys. The choice of proper Sn and Zr lines and the equipment's parameters, such as “integration start delay” and the spectrometer height, were fundamental to enhance the measurements. All samples were analyzed with X-ray fluorescence for a precise determination of their Sn concentration.
