Technician Support: ICP-MS research in the W. M. Keck Foundation Laboratory for Environmental Biogeochemistry, Arizona State University. Phase I.

EAR-0520648安巴尔这项提议将资助一名电感耦合等离子体质谱仪技术专家，以支持亚利桑那州立大学(ASU)新装修和配备的W.M.凯克环境生物地球化学基金会实验室的创新研究。该实验室的目标是利用质谱学的最新进展，促进地球科学、生命科学和化学交叉领域的研究。因此，新职位将支持开发和应用新的分析方法。这一职位的一个特别重点将是多收集器电感耦合等离子体质谱(MC-ICP-MS)的发展使新型同位素分析成为可能。计划工作的例子包括：利用古代沉积物中的钼同位素测量来重建大气和海洋中氧气量的变化；测量铁同位素以更好地了解这种生物基本元素的环境化学，以及探索铬同位素以追踪有毒污染物。除了支持具体的研究项目外，该奖项还将促进亚利桑那州立大学在同位素生物地球化学方面的一个充满活力的新项目的发展，该项目将汇集跨越多个学科的几个系、校、中心和研究所的研究人员。该奖项将使我们能够有效地将我们的新工具整合为研究生和本科生的综合培训，作为该计划的一部分。它还将增强亚利桑那州立大学教职员工指导博士后、非终身教职人员科学家的能力，其中几人参与了计划中的研究工作。

EAR-0520648AnbarThis proposal will fund an ICP-MS technical specialist to support innovative research in the newly renovated and equipped W.M. Keck Foundation Laboratory for Environmental Biogeochemistry at Arizona State University (ASU). The goal of this laboratory is to promote research at the intersection of the geosciences, the life sciences and chemistry by capitalizing on recent advances in mass spectrometry. The new position will therefore support the development and application of novel analytical methods. A special focus of this position will be new types of isotopic analyses made possible by the development of multiple collector inductively coupled plasma mass spectrometry (MC-ICP-MS). Examples of planned work include: the use of Mo isotope measurements in ancient sediments to reconstruct changes in the amount of oxygen in the atmosphere and oceans; the measurement of Fe isotopes to better understand the environmental chemistry of this biologically essential element, and exploration of Cr isotopes to trace toxic pollutants. In addition to supporting specific research projects, this award will enhance the development of a vibrant new program in isotope biogeochemistry at ASU that brings together researchers in several departments, schools, centers and institutes spanning a number of disciplines. The award will make it possible for us to effectively fold our new instruments into integrative graduate and undergraduate training as part of this program. It will also enhance the ability of ASU faculty to mentor post-Ph.D., non-tenure-track staff scientists, several of whom are involved in the planned research efforts.
