Technician Support: The NEPTUNE Multi-Collector ICP-MS in the WHOI ICP Facility

该项目为WHOI ICPMS设施中多接收器ICPMS NEPTUNE的新分析协议的开发提供支持。 这是一项为期三年的技术人员支助赠款的延续（第二阶段），该赠款自2004年以来促进了多项最先进分析方案的开发。 计划在2007-2008年供资期间开展以下分析工作：（1）利用镍作为大洋过程的新同位素示踪剂;（2）OIB斑晶中熔融包裹体的原位Pb和Sr同位素分析;（3）利用瞬态激光信号的低水平Os同位素分析;（4）硅酸盐和碳酸盐的原位Mg同位素分析;（5）海洋鱼类耳石中富集同位素标记的检测，（6）海水的低水平铁同位素分析，（7）天然铁同位素变异性，以及（8）使用在线氢化物发生的硒同位素测定。 我们预计，海王星ICPMS将在供资期结束后成为一个自我维持的业务。

This project provides support for the development of new analytical protocols on the multicollector ICPMS NEPTUNE in the WHOI ICPMS Facility. It is the continuation (phase 2) of a three-year technician support grant that facilitated the development of multiple state-of-the-art analytical protocols since 2004. The following analytical developments are planned for the 2007-2008 funding period: (1) Using nickel as a new isotope tracer of oceanic processes, (2) In situ Pb and Sr isotope analysis of melt inclusions in OIB phenocrysts, (3) Low-level Os isotope analyses using transient laser signals, (4) In situ Mg isotope analysis of silicates and carbonates, (5) Detection of enriched isotope tags in marine fish otoliths, (6) Low-level Fe-isotope analysis of seawater, (7) Natural rhenium isotope variability, and (8) Selenium isotope determinations using online hydride generation. We anticipate that the NEPTUNE ICPMS will be a self-sustaining operation after the end of the funding period.
