Urgent replacement of a sensitive and matrix tolerant ICP-MS for metal(loid) speciation

我们正在申请一台电感耦合等离子体质谱仪（ICP-MS），该质谱仪将与我们的液相色谱仪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。灵敏、可靠和基质耐受的ICP-MS将有力地支持几个资助/待定的研究计划（NSERC、ArcticNet、NIH、FRQNT），这些研究计划需要分析水样，包括分析原始湖泊和海洋沃茨中的金属（loil）浓度，确定金属（loid）形态，以及确定生物和人类材料中的金属（loid）。然而，我们目前检测含水样品中无机污染物浓度的能力受到了我们13年以上历史的ICP-MS频繁故障的严重影响;我们9年以上历史的ICP-MS几乎满负荷运行。目前，舍布鲁克大学没有额外的金属（loid）分析能力。收购一个敏感的，基质耐受性和国家的最先进的ICP-MS将巩固我们作为地球化学和环境地球化学领域的领导者的地位，并提供新的培训机会和研究方向在环境和健康科学。

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.
