Three new certified reference materials (CRM), certified for the platinum‐group elements (PGE), GPt‐8, GPt‐9 and GPt‐10 were developed based on the previous CRMs IGGE GPt‐1 to GPt‐7. The PGE concentration of GPt‐8 is about 1 ng g ‐1. GPt‐9 and GPt‐10 are ore samples with PGE concentrations of more than 1 μg g ‐1. A multi‐laboratory collaborative analysis scheme was adopted in the certification procedure, in which nine highly‐experienced institutes and laboratories participated. The samples were analysed for the six platinum‐group elements by nickel sulfide mini fire assay, with Te coprecipitation, and were determined by ICP‐MS. Osmium was determined by isotope dilution.
