This proposal requests funds to purchase an inductively coupled plasma-mass spectrometer (ICPMS) system for trace element and speciation analysis. The proposed system offers five key improvements over current equipment at UNM: a) improved detection limits, b) speciation ofmetals by HPLC separation, c) spot analysis of solid samples through use of existing laser ablation equipment, d) analysis of biological thin sections using a CryoCell, and e) isotopic analysis. This instrument will be integral to the research and training missions at UNM in areas related to energy development, water resources, and protection of the environment, and human health. Knowledge gained from research conducted at UNM and students graduating from its academic programs will be key to permitting responsible development of energy resources as well as protection of human health and environment in the arid southwest.

该提案要求提供资金购买用于痕量元素和形态分析的电感耦合等离子质谱仪(ICPMS)系统。拟议的系统对UNM的现有设备进行了五项关键改进：a)提高了检测下限，b)通过高效液相色谱分离实现了金属的形态分析，c)利用现有的激光消融设备对固体样品进行了现场分析，d)使用CryoCell对生物薄片进行了分析，e)进行了同位素分析。该文书将是联合国大学在能源开发、水资源、环境保护和人类健康领域的研究和培训任务的组成部分。从UNM进行的研究和从其学术项目中毕业的学生获得的知识将是在干旱的西南地区负责任地开发能源以及保护人类健康和环境的关键。
