Theoretical Study of Rare Earths Interferences in Inductively Coupled

A theoretical estimate of the thermal properties of polyatomic ions which can interfere with rare earth elements during the analysis process using the inductively coupled plasma mass spectrometer ICP-MS were studied. The ionization energies and heats of formation of the selected species at 0K and 298 K of the expected reactions to occur under the effect of plasma conditions in ICP-MS, are calculated using Gaussian 03 software.
