Acquisition of GC/MS for Advanced Undergraduate Laboratoriesand Undergraduate Research

该部门正在购买Finnigan MAT Magnum气相色谱/质谱仪（GC/MS）加数据处理系统。 此次购买包括一个62，000化合物数据库，允许学生对GC分离的未知物质的质谱数据进行计算机匹配。 目前正在进行几项新的实验，以利用该设备的能力。 实验涉及香料化学，化妆品添加剂，聚合物样品中的增塑剂，以及分离和隔离问题。 这些实验被用于初级和高级化学专业的高级实验室课程。 该设备也可供在本科研究计划注册的学生使用。 该设备允许高级化学专业的学生体验GC/MS技术，因为它是由实践化学家在现代实验室中使用的。

The department is purchasing a Finnigan MAT Magnum Gas Chromatograph/Mass Spectrometer (GC/MS) plus data handling system. This purchase includes a 62,000 compound database that allows students to do computer matching of mass spectral data of unknowns separated by the GC. Several new experiments are being used to take advantage of the capabilities of the equipment. The experiments involve flavor chemistry, cosmetic additives, plasticizers in polymer samples, and separation and isolation problems. These experiments are being used in upper-level Advanced Laboratory courses taken by junior and senior Chemistry majors. The equipment is also available for use by students enrolled in the Undergraduate Research program. This equipment allows upper-level Chemistry majors to experience the GC/MS technique as it is used by practicing chemists in modern laboratories.
