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

0923080Cizdziel“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) 的提案，该仪器将位于密西西比大学 (UM) 化学与生物化学系。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，因为它具有所有 ICP-MS 中最高的灵敏度和最低的检测限。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。由于该地区没有此类仪器，因此它将作为一个区域性多用户开放获取设施进行运营，称为中南痕量元素研究中心 (MSCTER)。除了可以立即使用该仪器的密歇根大学教职人员之外，三小时车程内不同机构的许多研究人员也将利用该设施来推进他们的研究。拟议的设施不仅将促进密歇根大学的跨学科项目，还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，并将与 Co-PI 一起监督该设施，该设施将效仿其他成功的痕量元素分析设施，并根据用户经验和技术人员的参与程度按费率收取费用。

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.
