Effect of 0.0042 M Matrix ions with a range of masses on ICP-MS signals
for analyte ions (7Li+, 27Al+, 45Sc+, 59Co+, 103Rk+, 13*13a+, 20*Pb+, and 232Th+). (From
Ref. 1’74.)
of
second, reduces the number large droplets that remain incompletely desolvated
in the ICP, and allows more time for diEusion of ions radially outward from the
center channel of the ICP. As the concentration of matrix ions in the plasma gas
sampled by the mass spectrometer is reduced, the extent of space-charge-induced
analyte ion transmission loss is decreased.
