New Opportunities for HPLC and LC-MS in Chemistry Instruction

小行星9350989 化学和生物化学科学的教学计划正在通过增加新的实验而得到加强，这些实验是通过使用高效液相色谱（hplc）和液相色谱-质谱（lc-ms）而实现的。 一个高效液相色谱系统正在添加到我们目前的质谱仪教学实验室实验和学生的研究项目。 第二个正在与现有的hplc配对，用于其他实验室实验和研究。 在整个课程中，至少有九个新的实验被用于化学课程。 大多数新实验都是以一个“问题”为中心的实验练习，由学生组成的“研究小组”来解决。 几个新的实验是使用手性相色谱法分析化学反应过程中形成的镜像异构体。 此外，学生的本科研究机会也随着越来越多地使用hplc和lc-ms而增加。

9350989 Martin The instructional programs in chemistry and biochemical science are being enhanced by the addition of new experiments made possible by the use of high performance liquid chromatography (hplc) and liquid chromatography-mass spectrography (lc-ms). One hplc system is being added to our present mass spectrometer for instructional laboratory experiments and student research projects. A second is being paired with an existing hplc for other laboratory experiments and research. At least nine new experiments are being adopted for chemistry courses throughout the curriculum. Most of the new experiments are sets of laboratory exercises centered on a "problem" to be solved by a "research team" of students. Several of the new experiments are using chiral phase chromatography for analysis of mirror image isomers formed during chemical reactions. In addition, student undergraduate research opportunities are increasing with more access to hplc and lc-ms. ***
