“…The channels associated with the 14 elements routinely measured on the SIMAAC system (Mn, Zn, Fe, Cu, Cr, Ni, Co, Mo, Sn, V, Ca, Mg, Na, and K) were studied to see if they were subject to spectral interferences from 17 possible interferent solutions (Mn, Zn, Fe, Cu, Cr, Ni, Co, Mo, Sn, V, Ca, Mg, Ma, K, La, Cs, and Si). Predicted potential interferents were obtained from tables of atomic emission lines (17)(18)(19)(20) and atomic absorption lines (2, 21,22). A total of 67 potential interferences were identified with iron being the leading candidate as an interferent.…”
