King, H. G.

A rapid spectrochemical method, involving the application of a condensed spark to finished or semifinished uranium metal surfaces, was developed to analyze large numbers of parts (50 or more in a single day) for up to nine specification impurity elements. No sampling or preparation is required, and the on-site analysis is carried out by transporting the spectrograph and source to the production area. The procedure is used for process control and is supplemental to the more refined pyro carrier spectrochemical analysis used for product certification. Elements determined by the large quartz prism spectrograph include: copper, iron, molybdenum, nickel, niobium, titanium, silicon, and zirconium. Carbon is determined by a very slight change in procedure. (auth)
