A gas chromatograph coupled to a mass spectrometer (GC-MS) will be used in most of the research as well as for a module in a new chemical engineering laboratory course supporting improvement of the curriculum. In research, the system provides a substantial enhancement to the existing studies into chemical mechanisms in high-temperature hydrocarbon reaction systems and the development of novel diagnostics and reaction processes for these systems. Current projects that will use this equipment include catalytic combustion of methane and large hydrocarbons, higher hydrocarbon and soot production in flames, mechanisms for oxidation of aromatic hydrocarbons, fuel processing reactions, structure-reactivity relationships for nanoporous materials and more recently growth of carbon nanotubes in flames and using catalytic template reactors. In all of these systems the complex product mix with multiple species at each mass requires a multidimensional analysis technique-a task for which the requested GC-MS system is well suited. Enhanced capabilities will include high scan rate for transient coupling studies, faster throughput, larger mass range and the ability to export data for analysis, plus dual MS detectors including both electron impact and chemical ionization. With the majority of students going on to graduate and professional schools, a large portion of the mission is exposing undergraduates to research. As part of the departmental development a new research laboratory course that will include modules in the laboratories of individual PIs is planned. The experiments using the proposed GC-MS would be appropriate for this course providing training in separation techniques, chemical kinetic analysis, quantitative methods and data analysis. The GC-MS would facilitate the incorporation of undergraduates into our research projects due to the ease of operation of the requested system and reasonably straightforward analysis.

气相色谱仪与质谱仪 (GC-MS) 联用将用于大部分研究以及新的化学工程实验室课程中的一个模块，以支持课程的改进。 在研究中，该系统极大地增强了高温碳氢化合物反应系统化学机制的现有研究以及这些系统的新型诊断和反应过程的开发。目前使用该设备的项目包括甲烷和大分子碳氢化合物的催化燃烧、火焰中高级碳氢化合物和烟灰的产生、芳香族碳氢化合物的氧化机制、燃料加工反应、纳米多孔材料的结构-反应性关系以及最近在碳纳米管中的生长。火焰和使用催化模板反应器。在所有这些系统中，每个质量具有多种物质的复杂产品组合需要多维分析技术，而所需的 GC-MS 系统非常适合这项任务。增强的功能将包括用于瞬态耦合研究的高扫描速率、更快的通量、更大的质量范围和导出数据进行分析的能力，以及包括电子轰击和化学电离的双 MS 探测器。随着大多数学生进入研究生院和专业学校，使命的很大一部分是让本科生进行研究。作为部门发展的一部分，计划开设一个新的研究实验室课程，其中包括各个 PI 实验室的模块。使用建议的 GC-MS 进行的实验适合本课程，提供分离技术、化学动力学分析、定量方法和数据分析方面的培训。由于所需系统易于操作且分析相当简单，GC-MS 将有助于本科生融入我们的研究项目。
