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

该提案将资助一名ICP-MS技术专家，以支持亚利桑那州立大学（ASU）新装修和装备的W.M. Keck环境生物地球化学基金会实验室的创新研究。该实验室的目标是通过利用质谱法的最新进展，促进地球科学、生命科学和化学交叉领域的研究。因此，新的职位将支持新的分析方法的发展和应用。该职位的一个特别重点将是通过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。计划开展的工作包括：利用古代沉积物中的Mo同位素测量来重建大气和海洋中氧气量的变化；铁同位素的测量，以更好地了解这种生物必需元素的环境化学，以及Cr同位素的探索，以追踪有毒污染物。除了支持特定的研究项目外，该奖项还将加强亚利桑那州立大学同位素生物地球化学领域一个充满活力的新项目的发展，该项目汇集了多个部门、学校、中心和研究所的研究人员，涵盖了多个学科。该奖项将使我们能够有效地将我们的新仪器整合到研究生和本科生的综合培训中，作为该项目的一部分。它还将提高亚利桑那州立大学教师指导博士后的能力。这些科学家中有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.
