X-Ray Fluorescence Laboratory Upgrade

这笔资金将用于升级一台X射线荧光光谱仪，并改进圣路易斯华盛顿大学地球与行星科学系X射线荧光实验室的样品制备设施。此次升级将使这一设施能够以购买新仪器的一小部分成本获得最先进的分析能力，用于分析岩石和矿物中的主要和微量元素。XRF实验室是一个部门设施，对华盛顿大学社区的所有成员和来自中西部其他大学和学院的地区用户开放，包括皮尤本科院校联盟的成员。

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.
