With support from the Chemical Measurement and Imaging Program in the Division of Chemistry, Professor Graham Cooks at Purdue University and his group will be studying the reactions of organic ions and the collection of their products in the open laboratory environment. Technological applications of chemistry depend upon both chemical reactions and on chemical analysis. Typical chemical reactions include those involved in making drugs, improving plastics, and breaking down biomass for new fuels. Typical chemical analyses include monitoring levels of specific drugs in blood, measuring pollutants in our rivers, and identifying the nature of white powders that are at the Senate Office building in envelopes. Mass spectrometry is one of the most widely used and sensitive methods of chemical analysis. This proposal involves attempts to use mass spectrometric methods to increase the rates of chemical reactions so as to make small quantities of sets of related materials quickly - that is to make libraries of compounds. These chemicals can be used for evaluating possible biologically active compounds that respond to certain enzymes or other purposes. Scaling up the chemistry that occurs in the mass spectrometer has the potential to generate new types of compounds by new routes, an example being fixing (incorporating) nitrogen into waxes (alkanes) by electrical discharges in air. Broader impacts of this project will be in education in the design and fabrication of new instrumentation. Chemical instrumentation is one of the core capabilities in science and technology and experience in building instrumentation will be a skill that will have impact over the careers of the graduate students and undergraduates involved in this project. Prototyping efforts that has produced new types of instruments and led to commercialization will be continued. An annual short course on chemical instrumentation for about 100 people will enhance skills in this area. Research results from the project will form the basis for developing experiments in organic and analytical teaching laboratories, helping to more effectively teach organic reactivity.

在化学系化学测量和成像项目的支持下，普渡大学的格雷厄姆·库克教授和他的小组将研究有机离子的反应及其产物在开放实验室环境中的收集。化学的技术应用既依赖于化学反应，也依赖于化学分析。典型的化学反应包括制造药物、改进塑料和分解生物质以获得新燃料。典型的化学分析包括监测血液中特定药物的水平，测量我们河流中的污染物，以及确定参议院办公大楼信封中白色粉末的性质。 质谱法是化学分析中使用最广泛和最灵敏的方法之一。 这个提议涉及尝试使用质谱方法来增加化学反应的速率，以便快速制造少量的相关材料组-也就是制造化合物库。这些化学品可用于评估可能的生物活性化合物，对某些酶或其他目的作出反应。 放大质谱仪中发生的化学反应有可能通过新的途径产生新类型的化合物，例如通过空气中的放电将氮固定（掺入）到蜡（烷烃）中。该项目的更广泛影响将是在新仪器的设计和制造方面的教育。 化学仪器是科学和技术的核心能力之一，构建仪器的经验将是一项技能，将对参与该项目的研究生和本科生的职业生涯产生影响。将继续进行制作原型的工作，这种工作已经产生了新类型的仪器，并导致商业化。每年为大约100人举办的化学仪器短期课程将提高这一领域的技能。 该项目的研究结果将成为有机和分析教学实验室开发实验的基础，有助于更有效地教授有机反应性。
