A spectrographic method is described for determining hafnium in zirconium. With a single exposure it is possible to cover the weight ratios of Hf/Zr from 0.001 to 1. The oxides mixed with a buffer are excited by a d-c 20amp arc and the spectrum recorded with a large quartz prism spectrograph. The hafnium concentration is determined from the intensity ratio of the line pairs Hf II 2641.4/Zr II 2856.06 and Hf I 2779.36/Zr I 2792.04 with coefficients of variation = 2.6 and 1.97%, respectively.
