Many laboratories have to perform the accurate analysis of numerous samples everyday, from service laboratories (such as Acme Analytical Laboratories Ltd) whose livelihood is to perform analyses to government agencies (such as the Canadian Food Inspection Agency, Health Canada and Environment Canada to name a few), which monitor food, drugs, water, etc. for our safety. However, limitations of the instruments that are used for this purpose often complicate the analyses by requiring additional steps, which unavoidably decrease the number of samples that can be analyzed each day. Furthermore, available instruments can barely detect several elements of interest. The goal of this collaborative research effort between the Department of Chemistry at Queen's University and Acme Analytical Laboratories Ltd (Acme) is to develop simple means of circumventing the main limitations of these instruments. To this end, several approaches will be optimized or developed to (1) decrease the lowest quantity of metal-containing species that can be measured in a variety of samples and (2) make the measurement largely independent of sample composition. This collaboration will benefit Queen's through new basic and applied research directions, operating support for their analytical laboratories, salary support for post-doctoral fellows and students, and publication of basic research results. Acme will benefit from new analytical techniques that they can successfully use for more effective analysis of geochemical samples, which should attract more clients. Canada will benefit from the simple strategies that can readily be implemented in all government, academic and industrial laboratories to enhance the quality of their results while increasing the number of samples that can be analyzed daily.

许多实验室每天都必须对大量样品进行准确分析，从以分析为生的服务实验室（如Acme Analytical Laboratories Ltd）到为我们的安全而监测食品、药物、水等的政府机构（如加拿大食品检验局、加拿大卫生部和加拿大环境部等）。 然而，用于此目的的仪器的局限性通常使分析复杂化，因为需要额外的步骤，这不可避免地减少了每天可以分析的样品数量。 此外，现有的仪器几乎无法检测到几种感兴趣的元素。 皇后大学化学系和Acme分析实验室有限公司（Acme）之间的这项合作研究工作的目标是开发简单的方法来规避这些仪器的主要限制。 为此，将优化或开发几种方法，以（1）降低各种样品中可测量的含金属物质的最低量，以及（2）使测量在很大程度上与样品组成无关。 这项合作将通过新的基础和应用研究方向，为他们的分析实验室提供运营支持，为博士后研究员和学生提供工资支持，以及出版基础研究成果，使女王大学受益。 Acme将受益于新的分析技术，他们可以成功地用于更有效地分析地球化学样品，这应该吸引更多的客户。 加拿大将受益于所有政府、学术和工业实验室都可以随时实施的简单战略，以提高其结果的质量，同时增加每天可以分析的样本数量。
