A New Method of Mathematical Correction of the Results of Analysis, Obtained by Inductively Coupled Plasma Mass Spectrometry, Ensuring the Elimination of the Interference of Doubly Charged Ions

Resumo

A new method of mathematical correction of the results of analysis, obtained by inductively coupled plasma mass spectrometry, for the elimination of the interference of doubly charged ion was proposed. This method bases on the use recording isotope signals in two operation modes of the spectrometer:standard and with using a collision cell (Kinetic energy discrimination/KED mode). The mathematical correction of the results of arsenic determination in model solutions was performed using two processes, standard and proposed in this paper. The accuracy and repeatability of the results were compared.
