MASS SPECTROMETER AND ACCESSORIES

这项赠款申请是为了购买双聚焦高分辨率 质谱仪和数据系统及附件，将用于 支持司法部调查人员的研究工作 明尼苏达大学化学专业。我们建议取代老化 1972年和1977年收购的仪器设备，正在变得越来越多 很难保持研究人员感兴趣的性能水平 需要，并添加LC-MS功能，该功能目前不能用于 这些用户。整合到部门的质谱学设施中， 新的仪器将提供标称和精确的质量能力 在EI、CI和热喷雾电离模式中，具有正负电离。 离子能力，使用各种样品进样系统(固体探针， 毛细管气相色谱、热喷雾高效液相色谱法)。

This grant request is for the purchase of a double-focusing high resolution mass spectrometer and data system and accessories which will be used to support the research efforts of investigators in the Department of Chemistry at the University of Minnesota. We propose to replace aging instrumentation acquired in 1972 and 1977 that is becoming increasingly difficult to maintain at a level of performance that research interests require, and to add LC-MS capability, which is currently not available to these users. Integrated into the Departmental Mass Spectrometry facility, the new instrumentation will provide nominal and accurate mass capabilities in EI, CI, and thermospray ionization modes, with positive- and negative- ion capabilities, using various sample inlet systems (solids probe, capillary GC, thermospray HPLC).
