Acquisition of a Reaction Cell/Quadropole ICP-MS System

该资助支持获取四极电感耦合等离子体质谱计（ICP-MS），以支持一系列需要高精度，低检测限微量元素分析的研究。ICP-MS将配置液相色谱（LC）模块，以允许分析特定的元素价。南佛罗里达大学（USF）地质、地理、环境科学与政策、海洋科学、人类学、生物学、土木与环境工程系的师生将受益于使用最先进的LC-ICP-MS进行研究，包括：1)天然水域中砷和硒物种的地球化学和毒理学；2)海洋热液系统化学动力学；3)火山弧组合地球化学和岩石学特征；4) tephrachronology;5)古环境元素代用物。ICP-MS系统将支持USF的本科和研究生教育，包括通过实验室课程和学生研究在地质学、地理学和环境科学与政策之间建立新的跨学科项目。该仪器将支持USF正在进行的和拟议的本科生研究经验（REU）站点项目，以及USF荣誉学院的实验室基础普通科学课程。将使用ICP-MS进行的很大一部分研究将直接应用于公共环境和健康问题。

0654214PichlerThis grant supports acquisition of a quadrupole inductively coupled plasma-mass spectrometer (ICP-MS) to support a range of research requiring high precision, low detection limit trace element analyses. The ICP-MS will be configured a liquid chromatography (LC) module to permit analysis of specific element valences. Faculty and students from the Departments of Geology, Geography, Environmental Science and Policy, Marine Science, Anthropology, Biology, and Civil and Environmental Engineering at the University of South Florida (USF) will benefit from access to a state-of-the-art LC-ICP-MS for studies including : 1) geochemistry and toxicology of As and Se species in natural waters; 2) marine hydrothermal system chemical dynamics; 3) geochemistry and petrology of volcanic arc assemblages; 4) tephrachronology; and 5) elemental proxies of paleoenvironments. The ICP-MS system will support undergraduate and graduate education at USF, including new cross-disciplinary programs between Geology, Geography and Environmental Science & Policy through laboratory courses and student research. The instrument will support of ongoing and proposed Research Experiences for Undergraduates (REU) Site projects at USF, and in lab-based general science courses in the USF Honors College. A significant portion of the research that will be conducted using the ICP-MS will have direct applications to public environmental and health concerns.
