Abstract
The “combined” FP method, which combines standardless FP method with empirical calibration, was applied to the analysis of Ir–Pt, Rh–Pt, Rh–Pd–Pt and Rh–Ir–Pt disk samples and Pt–Rh thermocouple wire. Four reference materials of binary Pt–Ir system, eight Pt–Rh systems, eight reference materials of ternary Pt–Ir–Rh system and 10 Pt–Rh–Pd systems were used for calibration of “combined” FP XRF method. Results of mentioned method agreed well with certified values, or ICP OES results respectively. For determination of elements, which were not present or certified in calibration standards (Ru in Rh–Pt–Pd disc and Fe in Pt–Rh thermocouple wire) the standardless FP method was used. This approach provides good results as well.
