Acquisition of Tandem Mass Spectrometry Instrumentation for Integrated Studies of Emerging Contaminants in Water

0722579这项核磁共振成像提案要求为两台串联质谱仪提供资金，重点研究水质及其生物地球化学和人为控制。重点放在新出现的污染物及其载体上，因为这些成分对水文循环的所有方面都产生了越来越大的影响，它们对水科学和工程构成了一些最复杂和广泛相关的挑战。亚利桑那大学(UA)四所学院的教员与亚利桑那州立大学(ASU)和北亚利桑那大学(NAU)的合作者正在建立一个致力于最先进的水分析的新的多用户设施，该设施将为这一环境科学、工程和毒理学这一交叉领域的当前和未来规划需求提供基石。核磁共振成像将包括在这个新设施中，将由18多名工程和科学学院合作人员使用，他们的研究和教学项目侧重于地下水、地表水、饮用水和废水。所有这些都有一个共同的目标，那就是表征和量化水体系中溶解和悬浮的物种。核磁共振请求是(I)液-质联用(LC-MS/MS)和(Ii)气相色谱-串联质谱(GC-MS/MS)。

0722579ChoroverThis MRI proposal requests funding for two tandem mass spectrometers with a research focus on water quality and its biogeochemical and anthropogenic controls. Emphasis is placed on emerging contaminants and their carriers, since these constituents are impacting to an increasing degree all aspects of the hydrologic cycle and they pose some of the most complex and broadly relevant challenges for water science and engineering. Faculty in four colleges at University of Arizona (UA), along with collaborators at Arizona State University (ASU) and Northern Arizona University (NAU), are establishing a new multi-user facility dedicated to state-of-the-art water analyses that will provide a keystone for current and future programmatic needs in this cross-cutting area of environmental science, engineering and toxicology. The MRI will be included in this new facility, and will be used by more than 18 engineering and science faculty collaborators with research and teaching programs focusing on groundwater, surface water, drinking water and wastewater. All share the common goal to characterize and quantify dissolved and suspended species in aqueous systems. The MRI request is for (i) liquid chromatography tandem mass spectrometry (LC-MS/MS) and (ii) gas chromatography tandem mass spectrometry (GC-MS/MS).
