We have studied for distribution and behavior siderophile and chalcophle elements in the mantle. For this purpose, we have developed : (1)new analytical methods for determination of platinum group elements (PGEs) ; (2)the new analytical methods for siderophile, chalcophile and lithophile elements except for PGEs ; (3)the new analytical method for precise determination of Re and Os isotope ratios for application to Re-Os isotope systematics.We first developed the new sample digestion method for determination of PGEs. In this study, we have designed an utterly new digestion vessel, which is cheap, simple and applicable up to 300C. We have proposed the patent. If this patent is accepted, this will be used all over the world, although the patent was just proposed in Japan, because of the lack of money. There was a reply from the Japanese Patent Office, and we replied and modified the patent.We also developed the new determination method for Bi,Tl,In,Li,Be,Rb,Sr,Y,Cs,Ba,La,Ce,Pr,Nd,Eu,Gd,Tb … More ,Dy,Ho,Er,Tm,Yb,Lu,Pb,Th and U using Q-pole type ICP-MS (ICP-QMS). We developed isotope-dilution internal standardization method (ID-IS). In this method, when the sample is digested with Sm spike, then, the elemental analysis is performed without knowing the exact dilution factor. We developed pseudo-FI method, in which only 0.1mL of sample solution is required for determination of these elements. Furthermore, we developed the determination method for Na,Mg,Al,P,Ca,V,Mn,Fe,Co,K,Sc,Ni,Cu,Zn and Ga using the same sample solution by sector type ICP-MS (ICP-SFMS). These methods are submitted to Geostandards and Geoanalytical Research. In addition, precise determination methods for B,Ti,Zr,Nb,Mo,Sn,Sb,Hf and Ta using ID-IS and pseudo-FI methods by ICP-QMS and ICP-SFMS were developed and submitted.We also developed new analytical methods for Re and Os isotope analysis using multiple collector ICP-MS (MC-ICP-MS). In this study, Os and Re of <1pg can be measured precisely, which can only be achieved by N-TIMS. This study has been accepted Analytical Chemistry (in press).Unfortunately, the development of analytical technique required far longer time than we had expected, thus the analysis of mantle samples are in future. Although, we have developed analytical methods, application will not take long time to accomplish. Less

研究了地幔中亲铁、亲铜元素的分布和行为。为此，我们发展了：（1）铂族元素分析的新方法;（2）除铂族元素外的亲铁、亲硫、亲石元素分析的新方法;（3）精确测定Re、Os同位素比值的新方法，并应用于Re-Os同位素系统学。在本研究中，我们设计了一种全新的消化容器，它是廉价，简单，适用于高达300 ℃。我们已经申请了专利。如果这项专利被接受，这将在世界各地使用，虽然这项专利刚刚在日本提出，因为缺乏资金。日本专利局对此进行了答复和修改，并开发了Bi、Tl、In、Li、Be、Rb、Sr、Y、Cs、Ba、La、Ce、Pr、Nd、Eu、Gd、Tb的新测定方法 ...更多信息 、Dy、Ho、Er、Tm、Yb、Lu、Pb、Th和U。建立了同位素稀释内标法（ID-IS）。在该方法中，当样品用Sm加标物消解时，则在不知道精确稀释因子的情况下进行元素分析。我们建立了伪流动注射法，只需0.1mL样品溶液即可测定这些元素。在此基础上，建立了扇形电感耦合等离子体质谱（ICP-SFMS）同时测定Na、Mg、Al、P、Ca、V、Mn、Fe、Co、K、Sc、Ni、Cu、Zn、Ga的方法。这些方法已提交给地质标准和地质分析研究。此外，还建立了ICP-QMS和ICP-SFMS等离子体质谱（ID-IS）和准流动注射（pseudo-FI）技术测定B、Ti、Zr、Nb、Mo、Sn、Sb、Hf和Ta的方法，并建立了多接收器ICP-MS（MC-ICP-MS）分析Re和Os同位素的新方法。本研究可以精确测量<1 pg的Os和Re，这是N-TIMS所能实现的。这项研究已被《分析化学》杂志接受（出版中），但由于分析技术的发展需要的时间远比我们预期的要长，因此地幔样品的分析还有待于进一步的研究。虽然我们已经开发了分析方法，但应用不会花费很长时间。少
