I have been asked to measure the composition of magnets dissolved in aqua regia. The analytes of interest are Al, Bi, Cr, Co, Cu, Dy, Gd, Ge, Au, Fe, Mn, Mo, Nd, Ni, Pd, Pt, Pr, Ag, Sr, Tb, Sn, V, Sn and Zr. I have an Agilent 7900 ICPMS and a Thermo 6500 iCAP OES available. I'm having trouble determining where to begin as there are so many interferences, analytes that need to be in or not be in HCl, some that need to have HF, some that run better on OES and others on MS. Any advice would be greatly appreciated!
