The elemental composition of natural waters, sediments, airborne dust, rainwater and marine microbiota contains information that is essential to an understanding the workings of Earth system, and its past and future trajectories, which are of fundamental importance to human society. Moreover, the ability to perform and interpret such chemical analyses is an essential part of the education and training of many scientific professionals within the field of ocean and earth sciences. Among the most commonly used methods for such elemental analyses is plasma source mass spectrometry, whereby a new generation of sample introduction systems coupled to a high-resolution inductively-coupled plasma mass spectrometer (HR-ICP-MS) allows routine elemental determinations in a wide variety of natural materials, over large ranges in elemental concentrations.This Major Research Instrumentation award will support the acquisition of a new, state-of-the-art HR-ICP-MS and dedicated sample introduction system, which will be housed in Old Dominion University's Department of Ocean, Earth and Atmospheric Sciences (OEAS). This equipment represents an essential replacement and upgrade of the 16-year-old system now in place, and is critically required to meet the current and future research demands of departmental faculty and graduate researchers, as well as provide essential training and education to OEAS postdoctoral researchers, graduate students and undergraduate majors. The new analytical equipment will be maintained and operated by a dedicated research specialist who is highly experienced in HR-ICP-MS analysis, and who will receive additional specific training in the use and maintenance of the new instrument and sample introduction system.

天然水域，沉积物，空气尘，雨水和海洋微生物群的元素组成包含对理解地球系统的运作及其过去和未来轨迹至关重要的信息，这些信息对人类社会至关重要。 此外，进行和解释这种化学分析的能力是海洋和地球科学领域许多科学专业人员的教育和培训的重要组成部分。 血浆源质谱法是，最常用的方法是，新一代样品介绍系统与高分辨率的电感耦合等离子体质谱仪（HR-ICP-MS）结合在一起，允许在各种自然材料中进行各种自然材料的奖励。 HR-ICP-MS和专用样本简介系统，该系统将安置在Old Dominion University的海洋，地球和大气科学系（OEAS）中。 该设备代表了现在已经到达16年历史的系统的必要替代品和升级，并且需要迫切需要满足部门教职员工和研究生研究人员的当前和未来研究需求，并为OEAS博士学位研究人员，研究生和研究生专业的专业提供了必要的培训和教育。 新的分析设备将由专门的研究专家维护和运营，他在HR-ICP-MS分析方面经验丰富，并将在使用和维护新仪器和样本介绍系统的使用和维护方面获得其他特定的培训。
