A method was devised for the determination of hafnium in zirconium oxide as reactor material. The "Sifter electrode-spark excitation technique" employed by C. Feldman and J. Y. Ellenburg was utilized and the sensitivity extended to 100 ppm hafnium. In this technique samples, finely ground and mixed with equal amounts of graphite powder, were put into the "sifter electrode" used as the upper electrode and excited in ARL multisource oscillating spark. A marked improvement was made in the ratio of signal to noise for hafnium spectral line, but the sensitivity was not sufficient. (auth)
