ICP Measurement

Both Th and U have very complex emission spectra and it is sometimes difficult to measure the element in the presence of one another or the other rare earth elements using ICP-OES. ICP-MS is the preferred measurement technique by analysts because the mass interferences are far less of a problem than spectral emission interferences:

Elem. ICP-OES Line (nm) ICP-OES (axial) DL (µg/mL) ICP-MS Line (amu) ICP-MS DL (ng/mL) Notes
Th 283.730 .007 232 .001 Monoisotopic
U 385.958 .001 238 .002
