In response to recent national mandates to improve undergraduate science education with innovations in teaching and laboratory experience for students, the department recognizes the need for modern equipment and computer applications in the undergraduate laboratory. The two distinct goals of this project are to integrate modern instrumental and computer methods throughout the chemistry curriculum and to achieve ACS accreditation for the new major. These goals are totally complementary, and somewhat synergistic, in their implementation. To move forward on this commitment, this project uses a benchtop gas chromatography/mass spectrometry (GC/MS) system to bring innovation and excitement into the laboratories at three different levels. The appeal of a GC/MS system is that it is a multipurpose instrument capable of capturing the imagination of students and motivating them in new and diverse ways. As an introduction, students observe demonstrations illustrating molecular behavior and are then guided through personal use of GC/MS in structure determination in the organic laboratory. In advanced laboratories, they study gas phase reactions and learn how to do more complex trace analyses and discover more about the power of the computer system. Finally, they have an opportunity to discover the value of GC/MS as a research tool and learn to appreciate its role in the undergraduate laboratory. The department sees a GC/MS system as an instrument well suited to motivating students to pursue a career in chemistry and as a tool that provides them with many skills they need to succeed in either industry or academia once they graduate.

为了响应最近国家通过创新教学和为学生提供实验室经验来改善本科科学教育的任务，该系认识到本科实验室需要现代设备和计算机应用。这个项目的两个不同的目标是在整个化学课程中整合现代仪器和计算机方法，并实现新专业的ACS认证。这些目标在执行过程中完全相辅相成，在某种程度上是协同的。为了推进这一承诺，该项目使用台式气相色谱/质谱仪(GC/MS)系统，在三个不同级别为实验室带来创新和兴奋。GC/MS系统的吸引力在于它是一种多功能工具，能够激发学生的想象力，并以新的和不同的方式激发他们的积极性。作为介绍，学生观察演示分子行为，然后通过在有机实验室中亲自使用GC/MS确定结构来指导学生。在高级实验室，他们研究气相反应，学习如何进行更复杂的痕量分析，并更多地了解计算机系统的能力。最后，他们有机会发现GC/MS作为研究工具的价值，并学会欣赏它在本科生实验室中的作用。该部门认为，GC/MS系统是一种非常适合激励学生在化学领域追求职业生涯的工具，也是一种工具，可以为他们提供毕业后在行业或学术界取得成功所需的许多技能。
