Urgent need to acquire introduction systems for high sensitivity and versatile analysis of environmental samples.

我们要求引进系统(即高灵敏度去溶雾化器、氢化物发生系统和高TDS引入和自动幻觉试剂盒)升级一个专门用于环境样品的高灵敏度和多功能分析的分析平台。拟议的项目可提高复杂矩阵分析的灵敏度，并进一步扩大可在极低浓度下进行分析的元素阵列。这一升级将有力地支持几个获得资助的研究项目(NSERC、ArcticNet)，这些项目需要分析高度多样化和复杂的环境、人类和生物基质中的多种金属(石油)S。我们目前的MS平台配置限制了我们研究复杂基质中浓度非常低的无机污染物和生物金属的能力。我们可以调查的元素的光谱也很有限，因为一些对环境和人类健康高度感兴趣的元素(例如，汞、锑、砷)在目前的配置下无法用我们的仪器进行适当的分析。目前，舍布鲁克大学没有可用的引进系统来升级我们的仪器，以达到我们支持快速发展和扩大的研究计划所需的灵敏度和多功能性。收购所要求的引进系统将巩固我们在生物地球化学和环境地球化学领域的领先地位，并在环境和健康科学方面提供新的培训机会和研究方向。

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.
