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
