The recent acquisition of a photodiode array ultraviolet-visible spectrophotometer is being used in the teaching of chemical principles and laboratory techniques to chemistry majors, other science majors and/or premedical students, and non-science majors at Davidson College. The speed of the instrument allows complete spectra to be acquired within seconds, displayed on a monitor, stored on disk, mathematically manipulated, and printed. The instrument is being used for kinetic experiments that require absorption values at more than one wavelength to be measured simultaneously. It also serves as a detector for high performance liquid chromatography, thus introducing students to principles of chromatography-spectrophotometry. Chemistry majors study the principles of operation of this computer-controlled instrument, with emphasis on concepts of digital electronics, instrument control, data file structures, and data transfer operations. The instrument is also used in student research projects involving organic photochemical reactions, the characterization of transition metal complexes, and investigation of the function of proteins.

最近购买的光电二极管阵列紫外可见分光光度计正被用于向戴维森学院化学专业、其他理科和/或医学预科学生以及非理科专业的学生教授化学原理和实验室技术。该仪器的速度允许在几秒钟内获得完整的光谱，在监视器上显示，存储在磁盘上，进行数学处理，并打印出来。该仪器用于动力学实验，需要同时测量多个波长的吸光度。它还可以作为高效液相色谱的检测器，从而向学生介绍色谱-分光光度测定法的原理。化学专业学习这种计算机控制仪器的工作原理，重点是数字电子学、仪器控制、数据文件结构和数据传输操作的概念。该仪器还用于学生研究项目，涉及有机光化学反应、过渡金属络合物的表征以及蛋白质功能的研究。
