The technique of decomposition of samples with a hardly soluble complex matrix (sintering with soda) for subsequent determination of trace element composition by high-resolution mass spectrometry with inductively coupled plasma is improved and tested. Analytical and methodological problems arising in the process of preparation of the samples under analysis for analysis are described, directions for their solution are indicated. The correctness of the developed sample preparation procedure has been verified by means of a comparative analysis of various methods applied to international certified standard rock samples.
