Abstract

A methodic of destruction of objects with hardly dissolvable matrix (earth materials, tableted medical products) for subsequent determination of microelements by high-resolution mass- spectrometry with inductively coupled plasma is developed. Analytical and methodical problems, appearing during of a sample collection and preparation at investigated objects, are described, the ways of their overcoming are proposed. The opportunity of carrying out of quantitative analysis of investigated objects after dissolution by means of using multielemental standard solutions is shown. Accuracy of a developed methodic of sample preparation was checked by analysis of standard samples of earth materials.
