Ultra-trace laboratory for legacy and emerging contaminants

该申请是为了购买一个系统，用于制备环境样品（水，雪，动植物组织，微生物，土壤，气溶胶），用于新的多学科平台，用于对遗留和紧急污染物进行超痕量分析，该平台将于2019年夏季在蒙特卡罗大学的新科学大楼中提供。该系统将允许小样品的精确称重，在超净气氛下制备消解溶液和标准溶液，以及样品的高温高压消解。如果没有这个准备系统，该平台将托管的高性能分析设施将无法有效使用，从而影响研究生的培训。******将使用该系统的团队由6名研究人员组成，他们提供丰富的多学科研究计划，在大气化学，水生和陆地生物地球化学以及生态毒理学的交叉领域，来自蒙特卡罗大学和麦吉尔大学的4个部门。这些研究人员是各自领域的活跃领导者，在过去22个月里发表了90篇论文，包括在《科学》、《自然地球科学》和《科学报告》上的论文。如果没有要求的系统，其中5个在新科学大楼的转移将导致更低的访问他们的高端仪器，这些仪器将被转移到新的平台。******这组研究人员非常积极地培训高素质人才，在过去6年中，在协作和多学科环境中培训了288人。有了这个系统，我们预计大约20名研究生将立即和强烈地使用新的分析平台。任何延误都将导致这一大批高素质人才的研究和培训活动放缓

This application is for the purchase of a system for the preparation of environmental samples (water, snow, animal and plant tissues, microorganisms, soils, aerosols) for a new multidisciplinary platform for the ultra-trace analysis of legacy and emergent contaminants that will be available during Summer 2019, in a new Science building at Université de Montréal. This system will allow precise weighing of small samples, the preparation of solutions of digestion and of standards under ultra-clean atmosphere, and the high temperature, high pressure digestion of samples. Without this preparation system, the high performance analytical facility that the platform will host will not be efficiently usable, with consequences for the training of graduate students.******The team that will use this system is formed of 6 researchers offering a rich and multidisciplinary research program, at the intersection of atmospheric chemistry, aquatic and terrestrial biogeochemistry and ecotoxicology, and coming from 4 departments at Université de Montréal and McGill University. These researchers are active leaders in their fields, with 90 published articles in the last 22 months, including papers in Science, Nature Geoscience et Scientific Reports. Without the requested system, the transfer of 5 of them in the new Science building will result in a lower access to their high-end instruments that will be moved in the new platform.******This group of researchers is very active in training highly qualified personnel, having trained 288 persons in the last 6 years in a collaborative and multidisciplinary environment. With this system, we anticipate that around 20 graduate students will immediately and intensely use the new analytical platform. Any delay will result in the slowdown of research and training activities for this large cohort of highly qualified personnel.**
