Incorporation of a Diode Array UV-Visible Spectrophotometer in the Undergraduate Curriculum

二极管阵列（DA）紫外可见分光光度计大大提高了本科生的实验室经验。该仪器用于三种主要的实验室环境：普通化学实验室、仪器分析和学生独立研究。在一般实验室中，学生使用DA UV-Vis。分光光度计在分析钢中锰的含量。这使得学生有机会在第一门化学课程中使用现代的、基于计算机的仪器。这有助于向学生展示仪器在化学中的作用、普遍性和力量。在仪器分析课程中，整合了“串联技术”的实验室模块，以演示与独立使用的组件技术相比，可以从串联技术中获得的额外信息。为了建立一个有凝聚力的实验室，有必要将光谱-电化学技术结合起来。一个理想的例子是紫外-可见光谱电化学，它需要DA UV-Vis。乐器。涉及学生的实验室和串联技术彼此之间及其与各自组成技术的比较，提供了对串联技术优势的广泛接触和欣赏。最后，本科研究是学生最好的教育经历之一，他们的时间是有限的。因此，这个项目是为了提供最有效的仪器，以确保一个富有成效的，积极的研究经验；紫外可见二极管阵列分光光度计广泛用于夏季研究项目以及学生研究人员在学年。该机构已为该项目提供了相当于国家科学基金会基金的金额。

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.
