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.

该项目为在WHOI ICPMS设施中的多策略ICPMS Neptune开发新的分析协议提供了支持。 自2004年以来，计划在2007-2008的融资期间计划以下分析发展，这是为期三年的技术人员支持赠款的延续（第2阶段）。使用瞬态激光信号的OS同位素分析，（4）原位MG对硅酸盐和碳酸盐的同位素分析，（5）在海洋鱼耳石中的富集同位素标签检测，（6）低水平的Fe-disotope在海水中进行了海水分析，（（7）使用自然rhenium rhenium rysopope变异性的生成selenium selenium selenious selenious selenious selenium selenious selenious。 我们预计Neptune ICPM将是资金结束后的自我维持的操作。
