Quantitative analysis of ternary alloy's content by means of laser induced plasma emission spectroscopy

Abstract EN

A quantitative elemental analysis of ternary alloy's content was carried out with laser induced plasma emission spectroscopy.

An energetic Nd : glass laser have been focused on a set of alloy targets at reduced pressure.

The intensity of UV and visible emission produced from laser-induced plasma was measured using ultra-high sensitive photon detection and counting system of high signal-to-noise ratio.

Ternary alloys of Sn-Bi-Pb were used with different composition and the observed photon emission intensity is found to be nonlinearly related to the concentration of the alloy's content.

The results were tested and demonstrated that the present sensitive spectrometer can be employed for rapid online estimation of the fractional content of ternary alloys with high accuracy.
