The Emission Spectrographic Carrier-Distillation Determination of Traces of Lead, Bismuth, and Tin in Nickel-Base Alloys

Volume 24, Number 3 (June 1970) Page 362-364

Atwell, M.G.; Golden, G.S.


A carrier-distillation dc arc emission spectrographic procedure is described for the determination of 0.5 to 20 ppm of lead, bismuth, and tin in nickel-base alloys. After conversion to an oxide, the sample is mixed with AgCl-LiF carrier and excited with 12 A current for 33 sec. Nickel oxide synthetic standards may be used. The coefficients of variation are less than 10%
