Abstract

The content of impurities of 33 elements (Li, Be, B, Na, Mg, Al, P, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb , Sr, Zr, Mo, Cd, Cs, Ba, Re, Tl, Pb, Bi, Th, U) in a praseodymium sample by inductively coupled plasma mass spectrometry (ICP-MS). The technique of sample dissolution and its preparation for analysis is given. Spectral interferences are eliminated by applying mathematical correction equations, a reaction-collision cell, and by adjusting the plasma power.
