The broad goal of this instrumentation proposal is to develop microchip flow injection capillary electrophoresis (MFI-CE) using fiber optic detection. Its research focus is on the development and deployment of new analytical methods for the analysis of metals and small molecules. This instrumentation development is a collaboration between PIs in Chemistry, Biochemistry, and Civil Engineering. The integration of FI-CE on a microfluidic format coupled to fiber optic detection is unique. The PIs' previous work designing CE on a microfluidic format, FI-CE, and FI using fiber optics will be integrated into one versatile instrument with small sample volume requirements and the robustness of a fiber optics detection system. The instrument will ultimately be used for: 1) Metal ion analysis and speciation, 2) Phosphorus-containing species analysis, and 3) Continuous flow enzyme microreactors. This research effort will provide undergraduate and masters students a solid background examining problems at the interface of chemistry and engineering. The proposed instrumentation project will involve students in the design and development of the instrument and will be part of a broad educational experience for students that will include scientific seminars, mentoring, and course advisement. The research projects planned for the participants are aimed at demonstrating the interdisciplinary nature of the techniques and its importance as a new and exciting instrument in solving broad scientific problems. Overall, this project will provide undergraduate and masters students a solid analytical chemistry and engineering design background with broad applications.

该仪器提案的总体目标是开发使用光纤检测的微芯片流注射毛细管电泳 (MFI-CE)。其研究重点是开发和部署用于分析金属和小分子的新分析方法。该仪器的开发是化学、生物化学和土木工程领域的 PI 之间的合作。 FI-CE 在微流体格式上的集成与光纤检测相结合是独一无二的。 PI 之前在微流体格式上设计 CE、FI-CE 和使用光纤的 FI 的工作将被集成到一台多功能仪器中，该仪器具有小样本量要求和光纤检测系统的稳健性。该仪器最终将用于：1）金属离子分析和形态分析，2）含磷形态分析，以及3）连续流酶微反应器。这项研究工作将为本科生和硕士生提供扎实的背景知识，研究化学和工程交叉领域的问题。拟议的仪器项目将让学生参与仪器的设计和开发，并将成为学生广泛教育经验的一部分，其中包括科学研讨会、指导和课程建议。为参与者计划的研究项目旨在展示该技术的跨学科性质及其作为解决广泛科学问题的新的、令人兴奋的工具的重要性。总体而言，该项目将为本科生和硕士生提供扎实的分析化学和具有广泛应用的工程设计背景。
