Chemical-Atomic-Emission Spectral Method of Ge, Au, and Hg Determination in Pure Metallic Ga

摘要

A method of Ge, Au, and Hg determination in Ga of high purity is considered. The method includes concentration of the impurities through partial chlorination of the matrix with gas Cl. The limit of Hg determination is x10~(-5) wt. percent and the limit of Au and Ge determination is 4 x 10~(-6) wt. percent. Simultaneous determination of Ni, Sn (4x 10~(-6)wt. percent) and Cu 4 x 10~ (-7) wt. percent) is possible.
