Abstract

In this study we summarized the rules of choosing internal sztenderds in ICP-MS technique. We represent some informative data about the concentrations of some potential internal sztenderds in foods. We have investigated the spectral interferences of the Be, Sc, Ge, Y, Zr, Rh, Pd, Ag, In, Sb, Te, Cs, Ta, W, Pt, Au and Bi, as potential internal sztenderd elements on Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Cd, Ba and Pb elements also in deionized water and ethanolic solvents. We have used and compared H2-He and NH3-He collision and reaction cell (CCT) gas mixtures, too. By the most common H2-He CCT gas mixture Ge can not be used for 75As (74Ge1H+), and Zr for 111Cd (94Zr17OH+) measurement. By the less common NH3-He CCT gas mixture Sc can not be used for 60Ni (45Sc14N1H+) measurement, Rh for 137Ba [103Rh (14N1H3)2+] measurement and Ge for 88Sr (74Ge14N) determination. In those cases, when the use of an internal sztenderd, which cause spectral interference, is necessary anyway, a CCT gas mixture change can solve the problem, except for Ge. Unless these situations, we offer all the other internal sztenderds for the suggested isotopes of the measured elements by the constructor (Thermo Scientific), just in the aspect of spectral interferences, specifically the monoisotopic or dominant isotopic rationed internal sztenderds. The ethanol has only a single effect in spectral interferences, correlated to aquareous solvent, by using W, as internal sztenderd for 61Ni isotope by H2-He CCT gas mixture, but it doesn't disturb the Ni measurement, since 60Ni is generally used. Moreover it should be mentioned that this kind of comparison of internal sztenderd elements should be investigated before application, because different spectral interferences derived by the vary in instrument parameter setting or manufacturer ought to have to known, thereby higher limit of detections can be avoided.
