N2 - Abstract: The contents of 25 elements were established in prospective reference materials, black shales SChS-1A and SLg-1A, using a developed analysis technique based on fusing samples with lithium metaborate and determining elements by external calibration with an internal standard on an ELEMENT high-resolution mass spectrometer. The passport characteristics of Russian reference materials of magmatic and sedimentary rocks SG-3, SGD-2A, ST-2A, SI-2, and BIL-1 and technical standards ZUK-1 and ZUA-1 have been clarified. New data of rare-earth elements were obtained for SI-2 and ZUA-1, which were missing during certification. Based on the inductively coupled mass-spectrometry analysis of standards SG-3 and SI-2 from 2005 to 2024, their applicability now has been confirmed. The new obtained ICP-MS results make it possible to expand the number of certified parameters of reference materials and clarify their results and can be used in analytical practice.
