Equipment for Sample Preparation and DC Plasma Analysis

等离子体发射光谱法最近已成为岩石、矿物、天然水和其他地质样品化学分析的首选技术，其中感兴趣的元素浓度范围从50%以上到十亿分之一以下。该提案要求提供购买一台直流电浆（DCP）发射光谱仪的一半费用，该光谱仪将由伊利诺斯-芝加哥大学地质科学系操作。DCP设备的分析能力将用于水系中毒素运输（Hg, As, Zn, Pb, Cd, Cu）的研究，伊zu- bonin盆地列岛的科学钻探，以及南海盆地的构造演化和岩浆作用（与中国科学院广州海洋研究所合作）。

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).
