Technical Support: Laser Ablation and Inductively Coupled Plasma Laboratories - Renewal

EAR-0549641平台该项目为波士顿大学地球科学系的多用户激光消融和感应耦合等离子体实验室提供技术支持。这些实验室包括Merchantek 213 nm激光消融微探头、VG PlmaQuad Excell电感耦合等离子体质谱仪和JY Ultima C电感耦合等离子体发射光谱仪。这些设施是地球科学部地球化学研究的骨干，支持地球科学研究所在俯冲旋回、熔体包裹体、海洋生物地球化学、海洋出口产品替代、超高分辨率古海洋学和硅酸盐风化等方面的积极研究。国际比较方案实验室还吸引了大量外部用户。事实上，60%的用户群在波士顿大学之外，涉及一系列主要由NSF资助的研究项目。大多数应用涉及对海洋沉积物和水柱颗粒物、火成岩、火山玻璃、斑晶和实验运行产品的高精度、多元素分析。新的方向包括独居石和锆石年代学，以及微量元素在风化环境中的行为。国际比较方案设施有很强的学生参与记录，40%以上的用户是学生。一项重要的活动是将研究生培养成下一代分析地球化学家。***

EAR-0549641PlankThis project supports a technical position for the multi-user laser ablation and inductively coupled plasma laboratories in the Department of Earth Sciences at Boston University. These laboratories include a Merchantek 213 nm laser ablation microprobe, a VG PlasmaQuad ExCell ICP-MS, and a JY Ultima C ICP-ES. The facilities are the backbone of geochemical research in the Department of Earth Sciences, supporting the PIs' active research in subduction cycling, melt inclusions, marine biogeochemistry, marine export production proxies, ultra-high resolution paleoceanography, and silicate weathering. The ICP laboratories also draw a large external userbase. In fact, 60% of the userbase is external to Boston University, and involves a wide range of predominantly NSF-funded research projects. Most of the applications involve high-precision, multi-element analysis of marine sediments and water column particulate matter, igneous rocks, volcanic glass, phenocrysts, and experimental run products. New directions include monazite and zircon geochronology, and trace element behavior in the weathering environment. The ICP facilities have a strong record of student involvement, with over 40% of the userbase being students. An important activity is the training of graduate students as the next generation of analytical geochemists. ***
