MRI: Acquisition of an Inductively Coupled Plasma Mass Spectrometer for Multidiscipline Research and Education

该奖项由主要研究仪器和化学研究仪器项目支持。罗文大学正在获得一台电感耦合电离质谱仪（ICP-MS），以支持于磊教授及其同事Kauser Jahan、Tabbetha Dobbins、Harold Connolly和James Grinias的研究项目。一般来说，质谱（MS）是用于鉴定和表征复杂样品中少量化学物质的关键分析方法之一。ICP-MS结合了一个高温和电离耦合等离子体源和一个质谱仪。ICP源将样品中的元素原子转化为离子。这些离子随后由质谱仪分离和检测。这是一种高灵敏度的分析技术，能够测量液体样品中极低浓度的金属和非金属。此次收购加强了大学和地区的研究基础设施。该仪器通过让不同的学生使用这种现代分析技术来扩大参与。它也被用于涉及化学、地质学和古生物学的学生和教师的拓展活动。分析结果有助于改善卡姆登和新泽西州南部其他社区的公共卫生和福祉。颁发质谱仪的目的是为了加强各级的研究和教育。它特别影响了金属碳化物的电化学氧化测量和锂离子电池固态电解质中硼氢化物的固体-电解质界面动态变化。该仪器还用于探索超临界流体色谱与ICP-MS相结合的高通量合成反应产物和催化剂测量。此外，它还有助于银洗脱薄膜的分析，用于抗菌材料的开发。质谱计也被用来通过分析铝26-镁26的同位素比率来了解太阳系。ICP光谱仪还用于跟踪和减少水中重金属污染的研究，以保护环境。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is supported by the Major Research Instrumentation and the Chemistry Research Instrumentation programs. Rowan University is acquiring an inductively coupled ionization, mass spectrometer (ICP-MS) to support the research projects in the groups of Professors Lei Yu and colleagues Kauser Jahan, Tabbetha Dobbins, Harold Connolly and James Grinias. In general, mass spectrometry (MS) is one of the key analytical methods used to identify and characterize small quantities of chemical species in complex samples. An ICP-MS combines a high-temperature and an ionization coupled plasma source with a mass spectrometer. The ICP source converts the atoms of the elements in the sample to ions. These ions are subsequently separated and detected by the mass spectrometer. This is a highly-sensitive analytical technique capable of measuring very low concentrations of metals and non-metals in liquid samples. The acquisition strengthens the research infrastructure at the university and regional area. The instrument broadens participation by involving diverse students with this modern analytical technique. It is also used in outreach activities involving students and faculty from Chemistry, Geology, and Paleontology. Analysis results are useful for improving the public health and well-being of Camden and other communities in Southern New Jersey.The award of the mass spectrometer is aimed at enhancing research and education at all levels. It especially impacts measurements of the electrochemical oxidation of metal carbides and the dynamic solid-electrolyte-interface change of borohydrides for solid state electrolytes in lithium-ion batteries. The instrumentation is also used for exploring supercritical fluid chromatography combined with ICP-MS for high-throughput synthetic reaction products and catalysts measurements. In addition, it contributes to the analysis of silver-eluting thin films for antimicrobial materials development. The mass spectrometer is also used to understand the solar system by analyzing the aluminum 26- magnesium 26 isotopic ratio. The ICP spectrometer is also employed in studies tracking heavy metal contamination and mitigation in water for environmental protection.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
