摘要: Abstract Using two axially-viewed inductively coupled plasma (ICP) systems that exhibited different behaviors to matrix effects, the sensitivity of Mg II 280.270 nm/ I 285.213 nm line intensity ratio ICP operating conditions and effects was compared observed for alternative ionic-to-atomic ratios such as Cd 226.502 nm/Cd 228.802 nm, Cr 267.716 nm/Cr 357.868 Ni 231.604 nm/Ni 232.138 Pb 220.353 nm/Pb 217.000 Zn 206.200 nm/Zn 213.857 ratios. Both robust non-robust were used. Some lines behaved differently, in particular lines, not only a function matrix, but also system. The II/Mg found remain good compromise follow changes conditions. use several confirmed axial viewing leads are particularly sensitive atomic lines. cannot be totally suppressed, even under conditions, regardless An minimize buffer Cs at 10 g l −1 .
