Upgrade of Inductively Coupled Plasma Mass Spectrometer System

该合同为Skidaway海洋研究所现有的电感耦合等离子体质谱计（ICP-MS）的系统升级提供了资金。这次升级将包括一个激光烧蚀系统，允许对固体样品进行多元素分析，一个电热汽化（ETV）炉，允许多元素检测限制约为1 ppb，使用消除干扰的“干”等离子体，以及一个mistral高效雾化器，在感应到ICP-MS之前溶解样品。利用这一先进的能力进行的调查包括鱼石层微量金属分析、稀土元素测定、海洋沉积物中的钍比、河流中微量金属的动员和运输、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将为此次收购提供超过100%的配套资金，升级后的仪器将成为地区环境、地质和海洋科学大学和研究机构的区域资产。＊＊＊

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. ***
