The Details of a Method for the Preparation of Solid Geological Samples for ICP-MS Multielement Analysis

详细

The technique of decomposition of samples with a poorly soluble complex matrix (sintering with sodium carbonate) for subsequent determination of trace element composition by the method of high resolution inductively-coupled plasma-mass spectrometry (ICP-MS) was improved and tested. Analytical and methodical problems that arise during the preparation of samples for analysis are described and directions for their solution are indicated. The correctness of the developed sample preparation procedure has been verified by comparative analysis of various procedures applied to the international certified rock reference samples.
