Comprehensive analysis for major, minor and trace element contents and Sr-Nd-Pb-Hf isotope ratios in sediment reference materials, JSd-1 and MAG-1
Nath, B.N.; Makishima, A.; Noordmann, J.; Tanaka, R.; Nakamura, E. (The Geochemical Society of Japan, 2009)In view of the requirement of a well-characterized and easily available aquatic sediment reference material, a comprehensive analysis comprising of fifty major, minor and trace elements as well as Sr–Nd–Pb–Hf isotopes ... -
New sequential separation procedure for Sr, Nd and Pb isotope ratio measurement in geological material using MC-ICP-MS and TIMS
Makishima, A.; Nath, B.N.; Nakamura, E. (The Geochemical Society of Japan, 2008)A new 3-step sequential separation chemistry for Sr, Nd and Pb from silicate samples, which is suitable for isotope analysis by MC-ICP-MS as well as TIMS, has been developed. The chemistry is designed to minimize the number ... -
Precise determination of Pb isotope ratios by simple double spike MC-ICP-MS technique without Tl addition
Makishima, A.; Nath, B.N.; Nakamura, E. (The Royal Society of Chemistry, 2007)A double-spike multicollector ICP-MS (DS-MC-ICP-MS) technique for Pb isotope analysis without Tl addition is established and its analytical performance is examined in detail. This simple DS-MC-ICP-MS technique using 20 ng ...
