A method is described for the determination of ultramicro quantities o-f osmium and iridium in samples of palladium and platinum. In order to avoid self- shielding differences between samples and standards during neutron irradiation, standards are prepared by the addition of very small kown amounts of osmium and iridium to analytical samples. In the analysis of palladium samples the Harwell Pile BEPO is used as the neutron source. To avoid spurious results due (n,p) and (n, alpha ) reactions, the Pile DIDO has had to be used for neutron-activation of samples of platinum. Each determination requires 0.1 g of sample, and radiochemical separations using carriers are used to isolate the induced osmium and iridium activities. Results are quoted for the osmium and iridium contents of some pure palladium and platinum samples. (auth)
