Abstract
Under the optimum experimental condition, the analytical spectral lines of the Fe and Ni trace elements in Pb-Cu alloy are determined in the experiment. The laser-induced breakdown spectroscopy(LIBS) calibration curves of the Fe and Ni trace elements are also determined in buffer gases He, Ar, Air and in vacuum. The standard fit errors for the calibration curves are in the range from 0.02 to 0.08.
