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.

对铁的适应催化流动分析（FIA）方法的初步工作表明，在停止流量模式下使用微顺序注射分析（USIA）产生检测限，可以在没有预浓缩的情况下在公海水平上确定铁。 夏威夷大学的科学家计划继续其有前途的初步工作，并充分评估该方法对痕量元素确定的潜力，并确定其对长期远程部署的适用性。 最初，研究人员计划完成对N，N-二乙基-P-苯二胺铁法对Zn的可用FIA方法进行顺序注射分析的适应。 开发新的分析痕量金属技术非常重要，尤其是在Geotraces计划的情况下。 关于更广泛的影响，将为一名研究生提供支持和培训作为该项目的一部分。
