And in percentage, it gives then: 58Ni: 65.05 60Ni: 26.76 61Ni: 1.24 62Ni: 4.05 Those values are in the range of the sample2 data for the Ni, except a slight deviation for 60Ni … more 60Ni found in the ash than calculated. FYI: There seems to be a noticeable error in the Sample 2 Ni ICP-MS Sum which might lend some argument to your analysis. It adds up to 100.2% so that 60Ni could really be 26.87% ... Still not there but closer. I need to debate the rest of your thoughts later, after some sleep. - Mark Jurich
