1463936 Kulp该补助金支持为纽约州立大学宾汉姆顿分校地质系购买配备高效液相色谱仪（HPLC）和激光消融（LA）微探针样品引入系统的四极杆检测电感耦合等离子体质谱仪（ICP-MS）。 HPLC前端将允许测定环境中痕量金属和类金属的形态，以研究痕量元素的地质微生物循环，特别是砷和锑，这些元素在某些价态下是有毒的。 LA探针将允许将蒸发岩和海洋碳酸盐托管流体包裹体引入ICP-MS中，以确定主要的（例如，Na、Mg、Ca、K）和微量元素（Ba、Br、Sr）的浓度及其比值，作为形成这些元素的海水化学成分的代表。 岩盐和海洋碳酸盐中流体包裹体化学的研究可以揭示整个中生代过去海洋化学的变化，对了解过去的气候和洋中脊热液过程具有重要意义。 该仪器还将支持与环境健康研究相关的矿物气溶胶中痕量金属浓度的研究，对了解岩浆房过程的火成岩成因的研究，以及用于先进燃料电池和锂离子电池工程的金属和氧化物纳米颗粒成分的研究。 该仪器将支持分析地球化学方面的研究生研究培训。 这种支持与国家科学基金会促进科学进步的使命是一致的，并可能通过提高对环境中潜在有毒微量金属物种的命运和运输的认识以及减轻环境健康影响和促进绿色能源技术工程的相关战略来促进国家繁荣和福利。

1463936KulpThis grant supports the acquisition of a quadrupole detection inductively coupled plasma mass spectrometer (ICP-MS) equipped with high performance liquid chromatograph (HPLC) and laser ablation (LA) microprobe sample introductions systems for the Department of Geology at SUNY-Binghampton. The HPLC front-end will allow for the determination of the speciation of trace metals and metalloids in the environment for investigations of the geomicrobiological cycling of trace elements, in particular Arsenic and Antimony, that are toxic at certain valence states. The LA probe will allow for the introduction of evaporite and marine carbonate hosted fluid inclusions into the ICP-MS for determination of major (e.g., Na, Mg, Ca, K) and minor (Ba, Br, Sr) element concentrations and their ratios as proxies of the chemistry of the seawater from which they formed. Studies of fluid inclusion chemistry in Halite and marine carbonates can shed light on the variability of past ocean chemistry throughout the Phanerozoic with implications for understanding past climate and mid-ocean ridge hydrothermal processes. The instrument will also support studies of trace metal concentrations in mineral aerosols with relevance to environmental health research, studies of igneous petrogenesis with implications for understanding magma chamber processes, and studies of the composition of metallic and oxide nanoparticles used for advanced fuel cell and Li-ion battery engineering. The instrument will support graduate student research training in analytical geochemistry. This support is congruent with NSFs mission of promoting the progress of science and may advance the national prosperity and welfare through advancing knowledge of the fate and transport of potentially toxic trace metal species in the environment and related strategies to mitigate environmental health impacts and in promoting green energy technology engineering.***
