Acquisition of a New XRF Spectrometer and Automated Sample Fusion Furnace

马萨诸塞大学阿默斯特分校的一台新的X射线荧光光谱仪这笔赠款用于购买一台新的X射线荧光（XRF）光谱仪，以取代马萨诸塞大学阿默斯特分校的两台旧的和故障的X射线光谱仪。目前的仪器已经连续运行了30多年。新仪器将继续成为麻省大学、该地区五所学院联盟和世界各地大学的学生和教师的重要资源。麻省大学的实验室已经为世界各地的科学家服务了30多年。现在，它将能够继续这一传统，成为美国科学界高质量XRF化学分析的宝贵和值得信赖的资源。这笔赠款将用于购买一台新的X射线荧光光谱仪，以取代马萨诸塞大学阿默斯特分校两台旧的和失败的X射线光谱仪。它还通过购买自动化熔融炉来支付升级的XRF样品制备设施。目前的两台X射线光谱仪已经为地质界服务了33年（西门子MRS-4）和23年（飞利浦PW 2400），并在此期间一直在持续运行。然而，现在两者都需要更换，因为更换零件不再可用。30多年来，马萨诸塞大学的XRF分析设施为马萨诸塞大学、邻近的五所学院以及美国岩石学、火山学和地球化学界的师生提供了高质量的XRF主要和微量元素分析。这一奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值进行评估来支持和更广泛的影响审查标准。

A New X-Ray Fluorescence Spectrometer at University of Massachusetts-AmherstThis grant pays for a new X-Ray Fluorescence (XRF) spectrometer to replace two old and failing X-ray spectrometers at UMass-Amherst. The current instruments have operated constantly for more than 30 years. The new instrument will continue to be an important resource for the students and faculty at UMass, the Five College consortium in the region and universities worldwide. The UMass laboratory has served scientists the world over for more than 30 years. It will now be able to continue the tradition as a valuable and trusted resource for high quality XRF chemical analyses to the U.S. scientific community.This grant pays for a new X-Ray Fluorescence spectrometer to replace two old and failing X-ray spectrometers at UMass-Amherst. It also pays for an upgraded XRF sample preparation facility through the acquisition of an automated fusion furnace. The two current X-ray spectrometers have served the geological community for 33 years (Siemens MRS-4) and 23 years (Philips PW2400) and have been in constant operation over this period. Now, however, both need to be replaced because replacement parts are no longer available. The XRF Analytical Facility at UMass has provided high quality XRF major and trace element analyses to faculty and students at UMass, the neighboring Five Colleges, and the U.S. petrological, volcanological and geochemical community for more than 30 years, and this can now continue into the future.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
