A review of the works dedicated to the application of the method of inductively coupled plasma mass spectrometry (ICP-MS) to the analysis of high-purity materials (semiconductors, metals, and their oxides) and published after 2004 is presented. The limitations of this method in the analysis of such objects are discussed. Advantages and disadvantages are demonstrated for three principal ways of the application of the ICP-MS method to the analysis of high-purity materials: direct analysis of a solid sample (laser ablation and injection of a sample in the form of a suspension); preliminary dissolution of an analyte sample; utilization of the approach separating analytes and matrix. © 2013 Pleiades Publishing, Ltd.

It is proposed to use doubly charged ions of the rare earth elements (REEs) to be determined in samples of neodymium, samarium, europium, and gadolinium by inductively coupled plasma mass spectrometry (ICP-MS) in order to reduce spectral interferences caused by oxide and hydroxide matrix ions. Optimal conditions for the registration of the doubly charged ions of REEs (resolution, depth of plasma sampling, generator output power, and argon flow in a nebulizer) are developed. The limits of determination for the REEs determined using singly and doubly charged ions in the samples of Nd, Sm, Eu, and Gd are evaluated. It is shown that the use of the signal from the doubly charged ions of odd isotopes allows reducing the limits of determination for Dy, Ho, Tm, and Er in neodymium, samarium, europium, and their oxides by one to two orders of magnitude. © 2013 Pleiades Publishing, Ltd.
