Sample Preparation - Dissolve PtPdRu alloy

 
I have some catalyst composed of PtPdRu/C. However, Pd and Ru are difficult to get dissolved even in aqua regia. Is there any solution to get their composition from ICP?

If an aqua regia digestion is not proving appropriate for Pd and Ru, then a fusion using KOH/KNO3 might be suitable, and we'd suggest 7 parts KOH to 1 part KNO3 and 1 part sample. A silver (Ag) crucible is recommended with a holding temperature of 650° C for 15-20 minutes.
