Реферат:	eng: The relevance of the study is caused by the need to develop new efficient sample preparation technique suitable for routine multiele/ ment ICP/MS analysis of geological samples which decreases time consumption and allows determining a wide number of elements in the range of single measurement using laser ablation (LA/ICP/MS). The main aim of the study is to compare metrological characteristics of two ICP/MS techniques, based on different sample preparation of silicate rocks – sample dissolution after melting with lithium metaborate and using prepared fused glasses for laser ablation. Objects: the international and Russian reference materials of natural rocks: basalts – BHVO/1, BHVO/2, BCR/2, granites – SG/1а, SG/3, gabbro SGD/1а, trap ST/1а. Methods: inductively coupled plasma mass spectrometry (ICP/MS) and laser ablation inductively coupled plasma mass spectrometry (LA/ICP/MS). Results of the study showed that the developed multielement ICP/MS and LA/ICP/MS techniques allow determining a wide number of elements in geological samples in the range of single measurement using low, medium and high resolution. Internal and matrix/matched external standards for decreasing/correction of matrix effects and instrumental drift are used. Comparison of the obtained results with values of six reference geological materials verified the accuracy of the techniques. The LA/ICP/MS technique is faster due to the lack of sample preparation, but has higher uncertainty and detection limits in comparison to the ICP/MS technique. © 2019 Tomsk Polytechnic University, Publishing House.
