项目摘要

The objective of this grant application is to provide researchers and users of the Characterization of Emerging Inorganic Pollutants/Indicators platform (CEIPIP), with a tool to enable to digest all samples types in a reproductible, complete, and coherent manner for inorganic analysis. The CEIPIP has already an extensive characterization platform with 2 ICP-MS/MS and 2 ICP-OES, but the sample preparation equipment that was purchased at its inception are now either impossible to repair (as parts are not supported by the vendors) or significantly damaged (which results in a high downtime). With over 50 different highly qualified personnel (HQP) currently using this instrumentation to support their active research, the sample preparation is the Achilles heel of the CEIPIP and has severely restricted our ability to analyze samples for their elemental compositions, especially for refractory elements or complex matrices (nuclear and e-wastes, peculiar sulfur deposit). In addition, as we are interested in the speciation and quantification of ultratraces, enrichment via chromatography or extraction is customary to digest samples. Thus, there is an URGENT need to provide the HQP of the CEIPIP with a robust sample digestion platform that is suited to the nature of the projects they are actively pursuing. For this reason, we are requesting three pieces of equipment (Focused Infrared Digester[FID], Microwave Digestion unit[MWD], and closed-vessel evaporator[CVE]) that can be coupled sequentially to provide a much-needed sample preparation capacity. Two of the requested equipment (FID and MWD) were part of the equipment previously available to CEIPIP users, but the obsolete and worn-out state of the decade-old equipment is jeopardizing our ability to perform state-of-the-art research related to inorganic constituents. Absence of such instrumentation strongly hinders the progression of our HQP and limited their capacity to generate data required to complete their research. Obviously, this platform will also be made available to all others graduate students and postdocs of the Science and Engineering faculty (over 300 researchers) as it has already been the case with the CEIPIP equipment. As many of our projects involves time and environment-sensitive species and nuclear materials, there is no possible alternative as the transportation and analysis of such substances is strongly limited in Canada, thus hindering our capacity to rely on external resources for the preparation of samples. Having this instrument is also very important for the training of HQP and for their future careers in analytical chemistry, nuclear and environmental sciences, earth sciences.
这项赠款申请的目的是为新兴无机污染物/指示剂平台(CEIPIP)的研究人员和用户提供一种工具,使其能够以可重复、完整和连贯的方式消化所有类型的样品,用于无机分析。CEIPIP已经有一个广泛的表征平台,有2个电感耦合等离子体质谱仪/质谱仪和2个电感耦合等离子体质谱仪,但最初购买的样品制备设备现在要么无法维修(因为供应商不支持),要么严重损坏(导致高度停机)。目前有50多名不同的高素质人员(HQP)正在使用该仪器支持他们的积极研究,样品制备是CEIPIP的致命弱点,严重限制了我们分析样品元素组成的能力,特别是分析难熔元素或复杂基质(核废料和电子废物、特殊硫磺沉积物)的能力。此外,由于我们对超种族的形态和定量很感兴趣,通过层析或提取进行浓缩是消化样品的惯常做法。因此,迫切需要为CEIPIP的总部提供一个强大的样品消化平台,以适应他们积极开展的项目的性质。为此,我们要求三台设备(聚焦红外消化器[FID]、微波消解装置[MWD]和闭合容器蒸发器[CVE])可以顺序耦合,以提供急需的样品制备能力。所要求的两台设备(FID和MWD)是CEIPIP用户以前可用的设备的一部分,但已有十年历史的设备陈旧和破旧正在危及我们进行与无机成分相关的最先进研究的能力。缺乏这类仪器严重阻碍了我们HQP的进展,并限制了他们产生完成研究所需数据的能力。显然,这个平台也将提供给科学和工程学院的所有其他研究生和博士后(超过300名研究人员),因为CEIPIP的设备已经是这样。由于我们的许多项目涉及对时间和环境敏感的物种和核材料,因此没有可能的替代办法,因为这类物质的运输和分析在加拿大受到严格限制,从而阻碍了我们依靠外部资源制备样品的能力。拥有这台仪器对HQP的培训以及他们未来在分析化学、核与环境科学、地球科学等领域的职业生涯也非常重要。
