Усовершенствована и апробирована методика разложения образцов и выделения сульфида серебра для последующего определения изотопного состава серы методом изотопной масс-спектрометрии. Описаны аналитические и методические проблемы, возникающие в процессе подготовки исследуемых образцов к анализу, указаны направления их решения. Правильность разработанной методики пробоподготовки проверена при помощи сравнительного анализа различных методик в трех лабораториях с использованием международных аттестованных стандартных образцов горных пород.

The method of sample decompounding and silver sulfide precipitation for determination of the isotopic composition of sulfur by isotope mass spectrometry has been tried out and improved. The analytics and methodology of preparing test samples for analysis are described, task variations are indicated. The validity of the developed method of sample preparation was verified by a comparative analysis of various methods in three laboratories using internationally certified standards.
