Autosampling Gas Chromatography-Mass Spectrometry in the Chemistry Curriculum

化学（12）一种新型气相色谱-质谱联用仪（GC/MS）配备了自动进样器、电子冲击和化学电离离子源，以及直接探针样品入口，将在有机化学、仪器方法、师生研究和两门非专业课程中实施。气相色谱/质谱实验改编自《化学教育杂志》，并衍生自主要研究文献。广泛的学生（理科生和非理科生，一年级到大四的学生）正在接触到不同复杂程度的GC/MS技术，目的是为了说明利用自动化的实验设计，并为学生提供生成和解释大型数据集的经验。气相色谱/质谱还被用于扩大可能的学生和教师研究项目的范围。

Chemistry (12) A new Gas Chromatography - Mass Spectrometer (GC/MS) equipped with an autosampler, electron impact and chemical ionization ion sources, and direct probe sample inlet is being acquired to be implemented in several courses, including organic chemistry, instrumental methods, student-faculty research, and two non-majors courses. GC/MS experiments are being adapted from the Journal of Chemical Education and derived from the primary research literature. A wide range of students (science majors and non-science majors, and first-year students through seniors) are being exposed to GC/MS techniques at varied levels of complexity with an eye towards illustrating the design of experiments that take advantage of automation and providing the students with experience generating and interpreting large data sets. The GC/MS is also being used to expand the range of possible student-faculty research projects.
