X-Ray Fluorescence Laboratory Upgrade

该合同将提供资金用于升级x射线荧光光谱仪，并改进位于圣路易斯华盛顿大学地球与行星科学系的x射线荧光实验室的样品制备设备。此次升级将使该设施能够实现最先进的分析能力，分析岩石和矿物中的主要和微量元素，而购买新仪器的成本只是其中的一小部分。XRF实验室作为一个部门设施向华盛顿大学社区的所有成员和其他中西部大学和学院的区域用户开放，包括皮尤大学本科机构联盟的成员。

This award will provide funding to upgrade an X-ray fluorescence spectrometer and to make improvements in the sample preparation facilities of the X-ray fluorescence laboratory in the Department of Earth & Planetary Sciences at Washington University in St. Louis. The upgrade will allow this facility to achieve state-of-the-art analytical capability for the analysis of major and trace elements in rocks and minerals at a fraction of the cost of purchasing a new instrument. The XRF laboratory is run as a departmental facility open to all members of the Washington University community and to regional users from other midwestern universities and colleges, including members of the PEW Consortium of undergraduate institutions.
