Improving Undergraduate Laboratory Instruction in Chemistry Through the Use of Energy Dispersive X-Ray Fluorescense Spectroscopy

最近获得的能量色散X射线荧光(EDXRF)光谱仪使该仪器可以用于萨吉诺山谷州立学院化学的分析/物理课程序列。学生有机会通过产生线谱来演示原子的特征，展示使用康普顿位移的X射线光子/电子相互作用与其他与吸收边、吸收和光电效应有关的效应之间的关系。由于EDXRF是一种快速、无损的技术，利用该仪器进行实验的学生将获得最新的定性和定量分析技术，并对原子结构和X射线的性质有基本的了解，这是进入各自科学领域所必需的。

The recent acquistion of an energy dispersive x-ray fluorescence (EDXRF) spectrometer allows this instrument to be used in the analytical/physical course sequence in chemistry at Saginaw Valley State College. Students have an opportunity to demonstrate the character of atoms through generation of line spectra, to show the relationship between x-ray photon/electron interactions using Compton shift and other effects relating to absorption edges, absorption and photoelectric effects. Since EDXRF is a rapid, non-destructive technique, students who carry out experiments utilizing this instrument acquire up-to-date qualitative and quantitative analytical techniques and a basic understanding of atomic structure and the properties of x-rays, required to enter their respective scientific fields.
