二极管阵列（DA）紫外-可见分光光度计具有很大的 增强了本科生的实验室体验。 仪器 在三个主要实验室环境中使用： 化学实验室，仪器分析，独立 学生研究。 在普通实验室，学生使用DA 紫外-可见分光光度计在锰分析中的应用 钢的含量。 这使学生有机会使用 现代化的，以计算机为基础的仪器， 当然了 这有助于向学生展示角色， 化学仪器的普及性和力量。 在 仪器分析课程，“串联”实验模块 技术”的集成，以证明额外的 从串联技术可以获得信息， 独立使用的组件技术。 为了发展 一个有凝聚力的实验室，有必要包括一个综合的 光谱电化学技术 一个理想的例子是 紫外-可见光谱电化学需要DA 紫外-可见仪器 实验室的区块涉及 学生和相互比较串联技术， 凭借其各自的组件技术， 接触和欣赏串联的优点 技术. 最后，本科研究是最好的之一 学生的教育经验，以及他们有时间 它是有限的。 因此，本项目是提供最 有效的仪器可以确保生产， 积极的研究经验;紫外可见二极管阵列 分光光度计在夏季科研中应用广泛 项目以及学生研究人员在学术期间 年 该机构为该项目提供了大量资金 相当于NSF的资金。

A Diode Array (DA) UV-Visible spectrophotometer has greatly enhanced the undergraduate laboratory experience. The instrument is used in three primary laboratory environments: general chemistry laboratory, instrumental analysis, and independent student research. In the general laboratory, students use the DA UV-Vis. spectrophotometer in the analysis of the manganese content of steel. This allows students the opportunity to use modern, computer based instrumentation in the first chemistry course. This helps to demonstrate to the students the role, pervasiveness and power of instrumentation in chemistry. In the Instrumental Analysis course, a laboratory block of "tandem techniques" is integrated to demonstrate the additional information one can obtain from a tandem technique as compared to the component techniques used independently. In order to develop a cohesive laboratory, it is necessary to include a combined spectroscopy-electrochemistry technique. An ideal example is ultraviolet-visible spectroelectrochemistry which requires a DA UV-Vis. instrument. The block of laboratories involving the student and comparison of tandem techniques with each other and with their individual component techniques provides broad exposure to, and appreciation for the advantages of tandem techniques. Finally, undergraduate research is one of the best educational experiences for students, and the time they have for it is limited. Therefore, this project is to providing the most effective instrumentation possible to ensure a productive, positive research experiences; the UV-Visible diode array spectrophotometer is used extensively in the summer research program as well as by student researchers during the academic year. The institution has contributed to this project in an amount equal to the NSF funds.
