We are requesting an inductively coupled plasma mass spectrometer (ICP-MS) that will be coupled to our liquid chromatography and our asymmetrical flow field-flow fractionation system in order to determine metal speciation in natural and biological samples. A sensitive, reliable and matrix-tolerant ICP-MS will strongly support several funded/pending research programs (NSERC, ArcticNet, NIH, FRQNT) requiring the analysis of aqueous samples, including the analysis of metal(loil)s concentrations in pristine lake and marine waters, determination of metal(loid) speciation, and determinations of metal(loid)s in biological and human materials. However, our present ability to examine inorganic contaminant concentrations in aqueous samples is seriously impacted by the frequent breakdown of our >13 years old ICP-MS; our >9 years old ICP-MS is at near full capacity. Currently, there is no additional capacity for metal(loid) analyses at the Université de Sherbrooke. The acquisition of a sensitive, matrix tolerant and state-of-the-art ICP-MS will consolidate our position as leaders in the biogeochemistry and environmental geochemistry fields and provide new training opportunities and research directions in the environmental and health sciences.

我们需要一台电感耦合等离子体质谱仪（ICP-MS），它将与我们的液相色谱和不对称流场-流分馏系统相结合，以确定自然和生物样品中的金属形态。一种灵敏、可靠和耐基质的ICP-MS将有力地支持几个已资助/未决的研究项目（NSERC、ArcticNet、NIH、FRQNT），这些项目需要分析水样，包括分析原始湖泊和海水中的金属（油）浓度，确定金属（样）形态，以及测定生物和人体材料中的金属（样）。然而，我们目前检测水样中无机污染物浓度的能力受到我们bbbb13年历史的ICP-MS频繁故障的严重影响；我们的bbbb9年ICP-MS已经接近满负荷运转了。目前，舍布鲁克大学没有额外的金属（loid）分析能力。获得灵敏、耐基质和最先进的ICP-MS将巩固我们在生物地球化学和环境地球化学领域的领导地位，并为环境和健康科学提供新的培训机会和研究方向。
