摘要
实验上研究了最佳实验条件下铅黄铜合金中Ni,Fe两种杂质元素的LIBS分析谱线,在氦气、氩气、空气和真空等4种环境中,测定了Ni,Fe两种杂质元素分析中的LIBS定标曲线,定标曲线的拟合标准偏差在0.02—0.08范围内.
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.
