“…The spectrometer was optimized to provide minimal values of the ratios CeO + /Ce + and Ba 2+ /Ba + and optimal intensity of the analytes. The concentrations of the elements were determined using the isotopes as follows: 7 Li, 11 B, 24,25,26 Mg, 27 Al, 31 P, 39 K, 42,44 Ca, 46−49 Ti, 51 V, 52 Cr, 54,57 Fe, 55 Mn, 59 Co, 60,62 Ni, 63,65 Cu, 64,66 Zn, 69 Ga, 75 As, 86,88 Sr, 96, 98 Mo, 105, 108 Pd, 107,109 Ag, 112,114,116 Cd, 121,123 Sb, 197 Au, 200,202 Hg and 206,207,208 Pb. Due to the presence of spectral polyatomic interferences on the isotopes of As and Pd, their concentrations were determined in DRC mode [36,37].…”
