Implementation of Instrumental Analysis in the UndergraduateCurriculum Using UV/Vis Spectroscopy

通过购置计算机化扫描紫外/维斯分光光度计和水净化系统，将仪器分析纳入大学化学和环境科学课程。 该仪器可用于水质、pH值、化学官能团吸收、蛋白质浓度、酶动力学、混合物的多组分分析、RNA浓度、结构异构化和分子转变的测定。 每个实验，主要改编自化学教育杂志和其他受人尊敬的来源，以适应每个课程的适当复杂性，旨在将重点从单纯的数据收集转移到立即分析和解释图形结果。 UV/维斯分光光度计和水净化系统用于普通化学、化学基础、生物化学、定量分析、物理化学和环境科学。 预期成果包括加强学生参与使用科学仪器收集实验数据，采用光谱分析的过程在真实的时间和紫外线范围，提高学生的能力，解释数据和趋势的图形分析，并提高学生的基本化学概念的理解。

Instrumental analysis is infused into the undergraduate chemistry and environmental sciences curricula through the acquisition of a computerized scanning UV/Vis spectrophotometer and water purification system. This instrumentation is used vigorously for the determination of water quality, pH, chemical functional group absorption, protein concentration, enzyme kinetics, multi component analysis of mixtures, RNA concentration, structural isomerization, and molecular transition. Each experiment, adapted primarily from the Journal of Chemical Education and other respected sources to the appropriate complexity of each course, is designed to shift the emphasis from mere data collection to immediate analysis and interpretation of graphical results. The UV/Vis spectrophotometer and water purification system are utilized in General Chemistry, Fundamentals of Chemistry, Biochemistry, Quantitative Analysis, Physical Chemistry, and Environmental Sciences. Expected outcomes include the enhanced student involvement in the use of scientific instrumentation to collect experimental data, the introduction of spectrographic analysis of processes in real time and at the UV range, increased student ability to interpret data and trends from graphic analyses, and improved student understanding of fundamental chemistry concepts.
