摘要：
A method of sample decompounding and silver sulfide precipitation for determination of the sulfur isotope composition using mass-spectrometry has been tested and improved. The analytics and methodology of preparing test samples for analysis are described and 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 rock standards.
