MRI: Acquisition of a High Resolution Inductively Coupled Plasma Mass Spectrometer for the Mid-South Region

0923080 Cizdoung“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“这是一项获得最先进的高分辨率电感耦合等离子体质谱仪（HR-ICP-MS）的提议，该质谱仪将位于密西西比大学（UM）化学和生物化学系。该仪器采用双聚焦（电磁）质量分析仪，是痕量和超痕量元素分析的首选技术，因为它提供了任何ICP-MS的最高灵敏度和最低检测限。此外，它具有通过高质量分辨率解决大多数同量异位素干扰的独特能力。由于该地区没有这样的仪器，它将作为一个区域性的多用户开放访问设施，被称为中南微量元素研究中心（MSCTER）。除了直接使用该仪器的UM教师外，三小时车程内不同机构的许多研究人员将利用该设施推进他们的研究。拟议的设施不仅将促进UM的跨学科项目，而且将鼓励中南地区研究人员之间的合作。PI在ICP-MS方面拥有丰富的经验，将与Co-PI一起监督该设施，该设施将模仿其他成功的微量元素分析设施，费用将根据用户经验和技术人员参与情况重新收取。

0923080Cizdziel"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."This is a proposal to obtain a state-of-the-art high resolution inductively coupled plasma mass spectrometer (HR-ICP-MS), which will be located at the University of Mississippi (UM), Department of Chemistry and Biochemistry. The instrument utilizes a doublefocusing (electric-magnetic) mass analyzer and is the technology of choice for trace and ultratrace elemental analysis because it offers the highest sensitivity and lowest detection limits of any ICP-MS. Moreover, it has the unique ability to resolve most isobaric interferences through high mass resolution. Because there are not such instruments in the area, it will be operated as a regional multi-user open access facility to be called the Mid-South Center for Trace Element Research (MSCTER). In addition to the UM faculty who have an immediate use for the instrument, a number of researchers at different institutions within a three hour drive will take advantage of the facility to advance their research. The proposed facility will not only facilitate interdisciplinary projects at UM but will encourage collaborations among researchers across the Mid-South. The PI has extensive experience with ICP-MS and together with the Co-PIs will oversee the facility, which will be modeled after other successful trace element analytical facilities, with costs being recharged at rates depending on user experience and technical staff involvement.
