MRI: Acquisition of a Quadrupole ICP-MS

这笔重大研究仪器(MRI)计划拨款中的TomascakFunds将支持购买一台四极检测电感耦合等离子体质谱仪(Quad ICP-MS)，以便对消化的矿物、岩石、土壤和沉积物、天然水和植物材料进行高精度的微量元素分析。四个电感耦合等离子体质谱仪将支持纽约州立大学奥斯威戈分校地质、化学和生物系的一系列研究，包括：混合岩和花岗岩岩石成因的地球化学调查；基于痕量金属替代品的与海洋和湖泊沉积有关的古氧化还原条件的调查；痕量金属对胰岛素生物化学影响的实验研究；以及湿地植被在土壤和水中隔离重金属的植物修复潜力研究。纽约州立大学奥斯威戈分校是一所非授予博士学位的机构。电感耦合等离子体质谱仪将为本科生和硕士研究生提供机会，获得高精度天然材料元素分析的最新技术实践经验。PIS打算在一些课程中纳入电感耦合等离子体质谱仪实验室练习，其中一门课程将包括对从刚果民主共和国提取的饮用水样本进行重金属分析，在刚果民主共和国，目前公众使用受污染的水供应与高婴儿死亡率有关。前进党联合计划与刚果政府合作，根据对所要求的电感耦合等离子体质谱仪获得的实验数据的分析，改进公共用水做法。***

0821302TomascakFunds from this Major Research Instrumentation (MRI) Program grant will support acquisition a quadrupole detection inductively coupled plasma mass spectrometer (quad ICP-MS) to allow for high precision trace element analysis of digested minerals, rocks, soils and sediments, natural waters and plant material. The quad ICP-MS would support a range of research across the Departments of Geology, Chemistry and Biology at SUNY-Oswego including: geochemical investigations of migmatite and granite petrogenesis; investigations of paleoredox conditions associated with marine and lake sedimentation based on trace metal proxies; experimental studies of the effects of trace metals on insulin biochemistry; and studies of the phytoremediation potential of wetland vegetation for sequestering heavy metals in soils and waters. SUNY-Oswego is a non-Ph.D. granting institution. The ICP-MS will afford undergraduate and M.S. students the opportunity to gain hands-on experience with state-of the-art techniques for high precision elemental analysis of natural materials. The PIs intend to incorporate ICP-MS lab exercises in a number of courses, one of which would include heavy metal analysis of drinking water samples retrieved from the Democratic Republic of Congo, where current public use of polluted water supplies is associated with high infant mortality. Co-PI Kadima intends to work with the government of the Congo to improve public water use practices based on analysis of experimental data obtained with the requested ICP-MS. ***
