项目摘要

We are requesting introduction systems (i.e., high-sensitivity desolvating nebulizer, hydride generation system, and high TDS introduction and autodillution kit) to upgrade an analytical platform dedicated to high sensitivity and versatile analysis of environmental samples. The proposed items allow for increasing the sensitivity of analysis in complex matrices and further expand the array of elements that can be analyzed at very low concentrations. This upgrade will strongly support several funded research programs (NSERC, ArcticNet) requiring the analysis of multiple metals (oil)s in highly diversified and complex environmental, human and biological matrices. Our current MS platform configuration limits our ability to investigate inorganic contaminants and biometals present at very low concentrations in complex matrices. We are also limited in the spectrum of elements we can investigate, because some elements of high interest for environmental and human health (e.g., Hg, Sb, As) cannot be properly analyzed by our instrument in their current configuration. Currently, there are no available introduction systems at the Université de Sherbrooke to upgrade our instruments to reach the sensitivity and versatility we need to support our fast-evolving and expanding research programs. The acquisition of the requested introduction systems 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.

我们要求介绍系统（即，高敏化材料雾化器，氢化物生成系统和高TDS介绍和自动化套件），以升级一个分析平台，专门针对高灵敏度和对环境样品的多功能分析。所提出的项目允许在复杂物质中提高分析的敏感性，并进一步扩大可以在非常低浓度的情况下分析的元素。该升级将强烈支持几个资助的研究计划（NSERC，ARCTICNET），需要在高度多样化且复杂的环境中分析多种金属（油），即人类和生物矩阵。我们当前的MS平台配置限制了我们研究复杂矩阵中非常低浓度的无机污染物和生物特征的能力。我们在可以调查的元素范围中也受到限制，因为我们对环境和人类健康感兴趣的某些要素（例如HG，SB，AS）无法通过我们的仪器当前的配置正确分析。目前，尚无介绍系统在Sherbrooke University升级我们的工具，以达到我们需要支持快速发展和扩展的研究计划所需的灵敏度和多功能性。收购所请求的简介系统将巩固我们作为生物地球化学和环境地球化学领域领导者的地位，并为环境和健康科学提供新的培训机会和研究指示。
