Emission spectral analysis of enamel glasses

Abstract

Table 1 gives the lines for the analysis of elements in a copper powder. It is clear that the copper lines differ only slightly from the lines of the experimental elements. The presence of > 0.005% of tin and lead is determined from the tin lines at 2839.9 A and the lead lines o at 2833 A. When the results of three parallel determinations had been averaged the reproducibility was increased 1.7-fold. Lack of correspondence among the reference specimens was ruled out since, three standards whose calculated composition was confirmed by chemical analyses [1] were melted for each glass composition. The
