Windom 9413534 This award provides funding for acquisition of a system upgrade to the existing Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) located at the Skidaway Institute of Oceanography (SkIO). This upgrade will consist of a laser ablation system that allows for multi-element analysis of solid samples, an ElectroThermal Vaporization (ETV) furnace that allows multi-element detection limits about one ppb using an interference eliminating "dry" plasma, and a mistral high-efficiency nebulizer that dissolves samples before induction into the ICP-MS. Investigations to be undertaken with this advanced capability include fish otilith layer trace metal analysis, rare earth element determinations, Thorium ratios in marine sediments, trace metal mobilization and transport in rivers, estuarine geochemical processes, sediment geochemistry, and groundwater discharge effects on coastal ocean chemistry. SkIO will contribute over 100% in matching funds for this acquisition and the upgraded instrument will serve as a regional asset for area environmental, geological and marine sciences universities and research institutions. ***

WINDOM 9413534该合同为购买位于斯基德韦海洋研究所的现有电感耦合等离子质谱仪的系统升级提供资金。这次升级将包括一个激光消融系统，它允许对固体样品进行多元素分析，一个电热汽化(ETV)炉，它使用一个消除干扰的“干”等离子体，允许多元素检测限制在1 ppb左右，以及一个米斯特拉尔高效雾化器，它在进入电感耦合等离子体-质谱仪之前溶解样品。将利用这一先进能力开展的研究包括鱼类表层痕量金属分析、稀土元素测定、海洋沉积物中的钍比率、河流中痕量金属的迁移和迁移、河口地球化学过程、沉积物地球化学以及地下水排放对沿海海洋化学的影响。SKIO将为此次收购贡献100%以上的配套资金，升级后的仪器将作为地区环境、地质和海洋科学大学和研究机构的一项地区资产。***
