The quantitative determination of 60% Sn in tantalum-tin mineral samples was carried out by line width method. When the concentrations of internal standard element Pb in all three standard series was 1%, 2%, and 3% respectively,the influence of Pb to the analytical results was discussed. The experimental results show that the different contents of the internal standard are different for both the accuracy and precision of spectral analysis.
