In this paper, the advantages of various analytical methods at home and abroad are analyzed. The determination of impurity elements in pure platinum is studied. By means of direct current arc excitation spectroscopy of powder samples, 21 impurity elements in pure platinum are measured at the same time. Standard deviation ≤ 25%. The method is simple, and has a wide range of application, which can be used for the analysis of impurity elements in 99 9% ~ 99 995% Pt
