Lithogenic isotopes of strontium (Sr), neodymium (Nd), and lead (Pb) are a powerful tool for the study of the composition and origin of pre-historic ceramics and their raw materials. Despite their use in classical geochronology and isotope-geochemical provenance studies of rocks and minerals, Sr, Nd, and Pb isotope ratios have so far scarcely been used

Isotope dilution analysis for speciation
Analytical and Bioanalytical Chemistry, 2003The advantages of isotope dilution analysis for speciation in the metal species are described. The species-unspecific mode of different species provides accurate and precise determination of the element, because the quantification parameter is an isotope ratio, in spite of an absoluted intensity.

Abstract Advances in molecular biology have resulted in a rapid increase in knowledge of the human genome. To date, a large number of polymorphic systems has been described, many of which, for example the human leukocyte antigen (HLA) system, have many alleles and play an important role in human disease. The accurate and rapid genotyping
