Equipment for Sample Preparation and DC Plasma Analysis

等离子体发射光谱分析技术最近已成为岩石、矿物、天然水和其他地质样品化学分析的首选技术，这些样品中感兴趣的元素的浓度从超过50%到不到十亿分之一。这项提议要求购买由伊利诺伊大学芝加哥分校地质科学系运营的直流等离子体(DCP)发射光谱仪的一半成本。DCP设备的分析能力将用于研究水系中的毒素迁移(汞、砷、锌、铅、镉、铜)、伊豆-博宁盆地群岛的科学钻探以及南中国海盆地的构造演化和岩浆活动(与广州中科院海洋研究所合作)。

Plasma emission spectrometrty has recently become the technique of choice for chemical analysis of rock, mineral, natural water and other geological samples where concentration of elements of interest range from over 50% to less than a part per billion. This proposal requests one half of the cost of acquiring a direct-current plasma (DCP) emission spectrometer to be operated by the Department of Geological Sciences at the University of Illinois-Chicago. The analytical capabilities of the DCP equipment will be used for research in toxin transport (Hg, As, Zn, Pb, Cd, Cu) in stream systems, scientific drilling in the Izu-Bonin basin archipelago, and the tectonic evolution and magmatism in the South China Sea basin (in collaboration with the Academia Sinica Institute of Oceanology-Guangzhou).
