Pacific centre for isotopic and geochemical research

太平洋同位素和地球化学研究中心(PCIGR)是不列颠哥伦比亚大学的一个主要区域地球化学分析设施，为来自加拿大西部大学(UBC、西蒙·弗雷泽大学、维多利亚大学)、政府机构、采矿业和国际研究界的研究人员的研究需求提供服务。根据NSERC的要求，我们已将MFA资助的地球和海洋科学部(PCIGR和AFES)的两个分析设施合并为一个。PCIGR是加拿大和美国独一无二的研究中心，提供对解决固体地球科学、环境科学和海洋学问题至关重要的分析仪器。该设施的中心是安装在新洁净室的七个质谱仪、一系列元素和气体分析器、三个新的化学清洁实验室和一个无机地球化学实验室的分析能力。目前正在研究的同位素和化学系统包括示踪剂中的放射性同位素(铅-铅、Rb-锶、Sm-ND、Lu-Hf)和地质年代学研究中的(U-Pb、Ar-Ar、(U-Th)-He)，地质和生物材料中的重稳定同位素(Fe、Mo、Cd、Mg、Cu、Zn)，海洋样品(沉积物、海水)中的铀衰变系列同位素，碳酸盐矿物、沉积物、水和气体中的轻稳定同位素(C、O、H、N)，以及地球、海洋和环境物质的微量元素特征。仪器、样品制备实验室和技术支持的结合是大批科学家和他们的学生进行研究的关键。要求提供资金，以部分支持对该设施的成功至关重要的基本研究人员。它们为新用户提供培训，允许灵活地适应用户的专门需求，并在开发新的分析方案方面发挥重要作用，所有这些都对确保PCIGR保持在地球化学研究的前沿至关重要。

The Pacific Centre for Isotopic and Geochemical Research (PCIGR) is a major regional geochemical analytical facility at the University of British Columbia serving the research needs of investigators from western Canadian universities (UBC, Simon Fraser University, University of Victoria), government agencies, the mineral industry, and the international research community. As per NSERC's request, we have merged the two MFA-funded analytical facilities in the Department of Earth and Ocean Sciences (PCIGR and AFES) into one. The PCIGR is a unique research centre both within Canada and the U.S. that provides analytical instrumentation critical for resolving problems in solid earth sciences, environmental sciences, and oceanography. The facility is centred around the analytical capabilities of seven mass spectrometers housed in new clean rooms, an array of elemental and gas analyzers, three new chemical clean laboratories, and an inorganic geochemical laboratory. Isotopic and chemical systems currently under investigation include radiogenic isotopes in tracer (Pb-Pb, Rb-Sr, Sm-Nd, Lu-Hf) and geochronological studies (U-Pb, Ar-Ar, (U-Th)-He), heavy stable isotopes in geologic and biologic materials (Fe, Mo, Cd, Mg, Cu, Zn), U-decay series isotopes in marine samples (sediments, seawater), light stable isotopes (C, O, H, N) in carbonate minerals, sediments, waters, and gases, and trace element characterization of earth, ocean, and environmental materials. The combination of instrumentation, sample preparation laboratories, and technical support is key to the research of a large number of scientists and their students. Funding is requested to partially support the essential research personnel that are vital to the success of this facility. They provide training for new users, allow the flexibility to accommodate the specialized needs of users, and play an important role in the development of new analytical protocols, all of which is essential to ensure that the PCIGR remains at the forefront of geochemical research.
