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

该合同将为圣路易斯华盛顿大学购买电感耦合等离子体发射光谱仪（ICP）提供部分资金。这台新仪器将被安置在该大学的地球与行星科学系，并将用于为该系的研究项目和教学计划提供所需的岩石和水样本的元素分析。目前正在进行的研究将利用该仪器的能力，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。ICP单元将提供对非常小的岩石、矿物和水溶液样品（少于20毫克）的痕量元素和主要元素组成进行全面分析的能力。这种样品现在已经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.
