MRI: Acquisition of an Inductively-Coupled Plasma Mass Spectrometer (ICP-MS) System at Missouri State University

该奖项由主要研究仪器项目和化学研究仪器项目支持。密苏里州立大学的西伦·里科教授和他的同事理查德·比亚戈尼、罗伯特·帕夫洛夫斯基、加里·米歇尔费尔德和梅丽莎·雷姆利获得了一台电感耦合等离子体质谱仪(ICP-MS)。通常，质谱学是用于鉴定和表征复杂基质中少量化学物种的关键分析方法之一。在一个典型的实验中，这些成分流入质谱仪，在那里它们被电离并测量离子质量。这种高度灵敏的技术可以检测和确定复杂混合物中的分子结构。使用电感耦合等离子体的电离允许检测存在于非常小浓度中的金属离子和几种非金属。此次收购加强了大学和地区的研究基础设施。它被许多学生使用，其中一些学生在理科中的代表性较低。研究领域包括分析、环境、地球化学和农业科学。国际电联-MS还有助于与当地其他大学的联系，如福音格尔大学和欧扎克技术社区学院。它被用于针对女性和第一代大学生的教育项目，因为密苏里州西南部没有学术机构具有电感耦合等离子体质谱仪的能力。授予电感耦合等离子体质谱仪旨在加强各级研究和教育，特别是在领域。它尤其影响对工程纳米材料的命运、运输、毒性和食物链转移以及植物/土壤与环境应激源的相互作用的研究。该仪器还用于分析养分和地球化学循环。质谱仪用于生物、食品、膳食补充剂和环境样品中的痕量元素分析。一些例子包括沉积物、土壤、火山岩、饮用水、废水、污水和植物。该奖项反映了NSF的法定使命，并通过使用基金会的智力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. Professor Cyren Rico from Missouri State University and colleagues Richard Biagioni, Robert Pavlowsky, Gary Michelfelder and Melissa Remley have acquired an inductively coupled plasma mass spectrometer (ICP-MS). In general, mass spectrometry (MS) is one of the key analytical methods used to identify and characterize small quantities of chemical species in complex matrices. In a typical experiment, the components flow into a mass spectrometer where they are ionized and the ion masses are measured. This highly sensitive technique allows detection and determination of the structure of molecules in a complex mixture. The ionization using an inductively coupled plasma allows detection of metal ions and several non-metals present in very small concentrations. The acquisition strengthens the research infrastructure at the university and regional area. It is used by many students, some underrepresented in science. Fields of study include analytical, environmental, geochemical, and agricultural sciences. The ICP-MS also contributes toward outreach to other local universities such as Evangel University and Ozark Technical Community College. It is used for educational program targeting women and first generation college students since no academic institution in southwest Missouri has ICP-MS capability.The award of the ICP-MS is aimed at enhancing research and education at all levels, especially in areas. It especially impacts studies of fate, transport, toxicity, and food chain transfer of engineered nanomaterials as well as plant/soil interaction with environmental stressors. The instrument is also used to analyze nutrient and geochemical cycling. The mass spectrometer is employed for trace elements analysis in biological, food, dietary supplements, and environmental samples. Some examples are sediments, soil, volcanic rocks, drinking water, wastewater, effluents, and plants.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.
