Acquisition of an Inductively Coupled Plasma Atomic Emission Spectrometer (ICP-AES)

该合同将为位于圣路易斯的华盛顿大学购买一台电感耦合等离子体发射光谱仪提供部分资金。这台新仪器将安装在该大学地球和行星科学系，并将用于提供该系研究项目和教学计划过程中所需的岩石和水样的元素分析。目前正在进行的利用该仪器能力的研究包括低温实验地球化学、沉积岩石学、矿石成因和地外地球化学等项目。电感耦合等离子体装置将能够全面分析极小样本(低于20毫克)的岩石、矿物和水溶液的痕量和主要元素组成。这样的样本现在超出了该部目前的分析系统的能力。

This award will provide partial funding toward the acquisition of an inductively coupled plasma emission spectrometer (ICP) by Washington University in St. Louis. The new instrument is to be housed in the University's Department of Earth and Planetary Sciences and will be used to provide elemental analysis of rock and water samples needed in the course of the Department's research projects and teaching programs. Currently active research that will be making use of the instrument's capabilities include projects in low temperature experimental geochemistry, sedimentary petrology, ore genesis, and extraterrestrial geochemistry. The ICP unit will provide the capability to completely analyze the trace and major element composition of very small samples (less than 20 milligrams) of rocks, minerals and aqueous solutions. Such samples are now beyond the capability of the Department's current analytical systems.
