Acquisition of a Reaction Cell/Quadropole ICP-MS System

0654214 Pichler该拨款支持购买四极电感耦合等离子体质谱仪（ICP-MS），以支持一系列需要高精度，低检测限痕量元素分析的研究。 ICP-MS将配置液相色谱（LC）模块，以允许分析特定元素的化合价。 来自南佛罗里达大学（USF）地质学、地理学、环境科学与政策、海洋科学、人类学、生物学以及土木与环境工程系的教师和学生将受益于获得最先进的LC-ICP-MS的研究，包括：1）天然沃茨中As和Se物种的地球化学和毒理学; 2）海洋热液系统化学动力学; 3）火山弧组合的地球化学和岩石学; 4）火山岩年代学; 5）古环境的元素代用指标。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，地理学和环境科学政策之间建立新的跨学科课程。 该仪器将支持正在进行的和拟议的研究经验的本科生（REU）网站项目在USF，并在实验室为基础的一般科学课程在USF荣誉学院。 将使用ICP-MS进行的研究的很大一部分将直接应用于公众环境和健康问题。

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.
