项目摘要

Mass spectrometry plays a major role in many areas where molecular measurements are critical, such as the life sciences, the environmental sciences, energy, security, etc. Important characteristics of a mass spectrometer include the resolution and accuracy with which it can determine molecular masses and the range of masses accessible, as well as practical instrumental features such as size, weight, power consumption, and cost. With support from the Chemical Measurement and Imaging Program in the Division of Chemistry, Dr. Scott McLuckey and his group at Purdue University seek to develop a conceptually new and simple means for mass analysis that combines impressive performance capabilities with potentially small size, low weight, low power consumption and relatively low cost. The work promises to make high performance mass spectrometry much more widely accessible to scientists across a wide range of fields, while providing valuable training opportunities for graduate and undergraduate students.Dr. McLuckey is developing a relatively small electrostatic linear ion trap based on opposing ion mirrors. The instrument will be useful for high-performance mass spectrometry and tandem mass spectrometry applications either as a component of larger systems or as a stand-alone device. The work targets mass resolution in the tens of thousands in analysis times well under one second, with capabilities for tandem mass spectrometry experiments using several dissociation methods. The net result will be a highly flexible and powerful tool that is simple enough to be built in academic laboratories for support of specialized experiments. It may also be attractive for commercial development to support a wide range of commonly performed experiments. Possible application areas range from field measurements (including extraterrestrial applications) to laboratory-based measurements that require high mass resolution and mass accuracy at relatively low cost. The relative ease with which dual-ion mirror devices can be fabricated will also facilitate the adoption of this technology in specialized research tools that are constructed to address research problems that cannot be addressed with commercially available instruments.

质谱在许多分子测量至关重要的领域中发挥着重要作用，例如生命科学，环境科学，能源，安全等。质谱仪的重要特性包括其可以确定分子质量的分辨率和准确度以及可获得的质量范围，以及实用的仪器特征，例如尺寸，重量，功耗和成本。在化学部化学测量和成像计划的支持下，普渡大学的Scott McLuckey博士和他的团队寻求开发一种概念上新的简单的质量分析方法，该方法将令人印象深刻的性能与潜在的小尺寸，低重量，低功耗和相对低的成本相结合。这项工作有望使高性能质谱更广泛地为科学家在广泛的领域，同时为研究生和本科生提供宝贵的培训机会。McLuckey博士正在开发一个相对较小的静电线性离子阱的基础上对离子镜。该仪器将是有用的高性能质谱和串联质谱的应用程序，无论是作为一个组件的大型系统或作为一个独立的设备。这项工作的目标是在分析时间内将质量分辨率提高到1秒以下，并具有使用多种解离方法进行串联质谱实验的能力。最终结果将是一个高度灵活和强大的工具，它足够简单，可以在学术实验室中构建，以支持专业实验。它也可能是有吸引力的商业发展，以支持广泛的共同进行的实验。可能的应用领域从实地测量（包括地外应用）到需要以相对较低的成本实现高质量分辨率和质量准确度的实验室测量。制造双离子镜装置相对容易，这也将有助于在专门的研究工具中采用这种技术，这些工具是为了解决商业上可用的仪器无法解决的研究问题而构建的。
