项目摘要

0116674BalesThis award supports a Major Research Instrumentation (MRI) Program project for one year of funding to develop a state-of-the-art continuous flow analysis (CFA) system that will be used for measuring concentrations of eight soluble chemical species (calcium, hydrogen peroxide, ammonium, formaldehyde, nitrate, sodium, chloride and sulfate) plus electrical conductivity in polar ice cores. The system will be designed for use in either the laboratory or the field and will consist of a melter (to hold, feed, melt and monitor the core melting progress) and a liquid-flow system to distribute melted samples and mix with reagents. In addition, the system will have a detector to measure the various analytical streams and a data acquisition and processing system for manipulating the large amounts of data that will be produced. While the chemical principles used in the detectors are well established, the design of the overall system and the detailed instrumentation will be entirely new. This new instrument will enable U.S. ice core scientists to remain at the forefront of technology and will increase the quality and rate at which new ice core records can be produced. The access to new ice core records which will be produced by this instrument should result in a better understanding of climate and atmospheric chemistry.
该奖项为一项主要研究仪器(MRI)计划项目提供为期一年的资助,用于开发最先进的连续流分析(CFA)系统,该系统将用于测量极地冰芯中8种可溶性化学物质(钙、过氧化氢、铵、甲醛、硝酸盐、钠、氯化物和硫酸盐)的浓度以及电导率。该系统将被设计用于实验室或现场,并将包括一个熔体(保持、喂料、熔化和监测核心熔化过程)和一个液体流动系统,以分发熔化的样品并与试剂混合。此外,该系统将有一个检测器来测量各种分析流和一个数据采集和处理系统来操作将产生的大量数据。虽然探测器中使用的化学原理已经很好地确立了,但整个系统的设计和详细的仪器将是全新的。这台新仪器将使美国冰芯科学家保持在技术的前沿,并将提高新的冰芯记录的质量和速度。该仪器将产生新的冰芯记录,获取这些记录将有助于更好地了解气候和大气化学。
