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极大地增强了本科生的实验室体验。该仪器用于三个主要实验室环境：普通化学实验室、仪器分析和独立的学生研究。在普通实验室，学生使用DA UV-VIS。用分光光度计测定钢中的锰含量。这使学生有机会在第一堂化学课中使用现代的、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、普及性和力量。在仪器分析课程中，我们整合了一个“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，从串联技术中可以获得的额外信息。为了发展一个有凝聚力的实验室，有必要采用光谱-电化学相结合的技术。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。学生参与的实验室区块以及串接技术彼此之间的比较以及与其各自组件技术的比较使学生能够广泛接触并欣赏串接技术的优势。最后，本科生的研究是学生最好的教育经历之一，但他们花在这上面的时间有限。因此，该项目旨在提供尽可能最有效的仪器，以确保富有成效的、积极的研究体验；紫外可见二极管阵列分光光度计在暑期研究项目中以及在学年期间被学生研究人员广泛使用。该机构为该项目提供了相当于NSF资金的捐款。

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.
