摘要: Application of Sr in tracing animal and human migrations as well as sources of meat products is a new research field. A method for Sr-87/Sr-86 ratio measurements in meat products has been established through detailed experimental studies using different techniques of sample digestion, including acid dissolution, microwave digestion and ashing. Ashing using quartz crucible, graphite crucible and quartz crucible were tested. The methodology established includes sample ashing using quartz crucible, ion exchange separation using cation resin, and Sr-87/Sr-86 measurement by thermal ionization mass spectrometry. The method for Sr-87/Sr-86 ratio measurements in meat products can be used for the analysis of other organic samples.
