The aim of every chemical analysis is to achieve accurate results. In ICP-MS, however, a large number of molecular species overlap with analyte masses. Those are either remains of incomplete destruction of molecules introduced into the ICP, or recombination products of ions generated by the plasma. Several techniques have been developed to overcome the spectral interferences caused by such molecular ions, like optimized sample introduction systems, high resolution mass spectrometers, and collision/reaction cells.
