Abstract

Various techniques have been tested (multi-acid microwave decomposition and sintering with soda) for preparing samples for the analysis of ICP-MS for samples with a complex matrix including an organic component for the subsequent determination of the microelement composition. For research, we used samples of bottom sediments: terrigenous clay (SDO-1), volcanic-terrigenous silt (SDO-2), calcareous silt (SDO-3), ferromanganese nodules (SDO-5), Baikal silt (BIL-1) and complex sediment sample of Baikal (BIL-2). The most effective sample preparation methods for the studied rock type are proposed.
