New X-Ray Fluorescence Spectrometer for the University of Rhode Island XRF Laboratory

0236617Hermes 这笔赠款支持购买一台新型波长色散 X 射线荧光光谱仪 (XRF)，安装在罗德岛大学 (URI) 地球科学系的 XRF 实验室中。 新仪器将取代目前1983年购买的不起作用的能量色散系统。该公司不再提供对1983年仪器的升级和支持，最终，在2001年夏天，一个无法更换的“吹坏”X射线管决定了它的命运。 新的最先进的波长色散系统将极大地提高我们实验室的能力，包括分析几乎所有具有地质意义的元素的能力，并大大提高灵敏度和准确性。 该大学为新的 XRF 提供了一个翻新的实验室。 所有样品制备设备，包括破碎机、研磨机、助熔剂、压力机等均已就位，与 1983 年仪器使用时一样。自 1983 年以来，URI Geosciences XRF 设施已为新英格兰南部地区的许多科学家提供服务，为多达一百个研究项目提供高质量的主元素和微量元素数据。 该设施支持各种基础研究、30-40 篇研究生论文、无数本科生论文和研究项目，并为 URI 的垂直整合学习提供了持续的长期模型。 URI 地球科学 XRF 设施不仅增强了大学的研究/教育基础设施，而且还向地区学院和社区学院的学生和教师开放实验室，而这些地方没有先进且昂贵的研究实验室。 我们还与博物馆、国家犯罪实验室和其他团体合作，所有这些团体的组织中都有大量女性。 新设备将使该设施能够继续为 URI 以及新英格兰南部地区的各类科学家和应用提供服务。***

0236617HermesThis grant supports the acquisition of a new wavelength-dispersive X-ray Fluorescence Spectrometer (XRF) to be installed in the XRF laboratory at the University of Rhode Island (URI), Department of Geosciences. The new instrument will replace the current non-functioning energy-dispersive system originally acquired in 1983. Upgrades and support for the 1983 instrument are no longer available from the company, and finally, in the summer of 2001, a "blown" X-ray tube that could not be replaced sealed its fate. The new state-of-the-art, wavelength-dispersive system will greatly improve the capabilities of our laboratory, including the ability to analyze for nearly all elements of geologic significance, at greatly improved sensitivities and accuracy. The University has provided a renovated laboratory for the new XRF. All sample preparation equipment, including crushers, grinders, fluxers, presses, etc. are in place as they were used with the 1983 instrument. Since 1983, the URI Geosciences XRF facility has served many scientists in the southern New England region, providing high-quality major and trace-element data for as many as one-hundred research projects. The facility supported a wide variety of basic research, 30-40 graduate theses, innumerable undergraduate theses and research projects , and provided an ongoing, long-term model for vertically integrated learning at URI. The URI Geosciences XRF facility not only enhances the research/education infrastructure of the university, but also provides a laboratory open to students and faculty at regional colleges and community colleges where sophisticated and expensive research laboratories are not available. We also have partnered with museums, the state Crime Laboratory, and other groups, all of which have substantial numbers of women in their organizations. The new equipment will permit the facility to continue to serve a diverse array of scientists and applications at URI as well as from the southern New England region.***
