A method is described for the determination of ultramicro quantities of arsenic and antimony in pure platinum. In order to avoid self-shielding differences between sampies and standards during neutron irradiation, comparators were prepared by the addition of very small known amounts of arsenic and antimony to analytical samples. Samples of 0.1-g of platinum were taken for the determinations, and a radiochemical separation procedure using carriers was employed to isolate the induced arsenic and antimony activities. Results of analyses of seven samples of platinum are given. Although contents of as little as 10/sup -8/ g of either arsenic or antimony were determined, the uitimate sensitivity of the method was not approached. (auth)
