Preliminary work on the adaptation of the catalytic Flow Injection Analysis (FIA) method for iron suggests that using micro sequential injection analysis (uSIA) in a stopped-flow mode yields detection limits that would enable the determination of iron at open ocean levels without preconcentration. Scientists from the University of Hawaii plan to continue their promising preliminary work and fully evaluate the potential of this methodology for trace element determinations, as well as establish its suitability for long term remote deployment. Initially, the researchers plan to complete their adaptation of the N,N-diethyl-p-phenylenediamine iron method to sequential injection analysis before adapting the available FIA methodology for Zn. Development of new analytical trace metal techniques is important especially in light of the GEOTRACES program. As regards broader impacts, one graduate student would be supported and trained as part of the project.

初步工作的适应铁的催化流动注射分析（FIA）方法表明，使用微序贯注射分析（USIA）在停流模式产生的检测限，使铁的测定在开放的海洋水平没有预浓缩。 来自夏威夷大学的科学家们计划继续他们有希望的初步工作，并充分评估这种方法用于微量元素测定的潜力，以及确定其是否适合长期远程部署。 最初，研究人员计划在采用锌的FIA方法之前，完成N，N-二乙基-对苯二胺铁方法对顺序注射分析的适应。 开发新的痕量金属分析技术非常重要，特别是在GEOTRACES计划的背景下。 至于更广泛的影响，作为该项目的一部分，将支助和培训一名研究生。
