This Earth Sciences Instrumentation and Facilities award supports the procurement of a Wavelength Dispersive X-ray Fluorescence Spectrometer (WD-XRF) for California State University, Bakersfield (CSUB), the sole comprehensive university within a 100-mile radius and a designated Hispanic-Serving Institution. The new WD-XRF, an analytical system, assesses complex matrix materials with a broad spectrum of light and heavy elements, ranging from trace to high concentration levels. The acquisition of this new instrument will enhance research capabilities across diverse disciplines at CSUB, including Geology, Engineering, Environmental Studies, Physics, and Agriculture. It plays an integral role in initiatives aimed at boosting minority student enrollment and retention, elevating educational achievements, and fostering research skills in Science, Technology, Engineering, and Math fields. The instrument also contributes to community outreach efforts, including the high school dual credit program.The new WD-XRF system is one fully automated benchtop XRF, featuring a 12-sample changer and sample spin capability for student use with minimal training. It eliminates the need for cooling water, reducing maintenance and ownership costs. With superior sensitivity and spectral resolution compared to Energy Dispersive XRF spectrometers, it rivals larger WD-XRF systems. Its introduction to CSUB will bring advanced technological capabilities, leading to research advancements in areas including upcycling of mine tailings, polymeric composite materials, agricultural-waste-derived catalysts for energy and resource recovery, paleoceanography, and paleoclimate. Beyond its technical capabilities, the instrument will pave the way for new research directions at CSUB, encouraging collaborative projects among faculty from different departments and facilitating partnerships with researchers from other institutions.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.

该地球科学仪器奖奖支持为加利福尼亚州立大学，贝克斯菲尔德（CSUB），100英里半径内的唯一综合大学和指定的西班牙裔服务机构的唯一综合大学，支持加利福尼亚州立大学的波长色散X射线荧光光谱仪（WD-XRF）。新的WD-XRF是一种分析系统，评估了具有广泛的轻质和重元素的复杂矩阵材料，从痕量到高浓度水平。获取该新工具将增强CSUB各种学科的研究能力，包括地质，工程，环境研究，物理和农业。它在旨在提高少数学生入学率和保留率，提高教育成就以及培养科学，技术，工程和数学领域的研究技能的旨在提高少数学生的入学和保留方面发挥了不可或缺的作用。该乐器还为社区推广工作做出了贡献，包括高中双学分计划。新的WD-XRF系统是一种全自动的台式XRF，具有12个样本的更换器和样本旋转能力，可用于学生使用最少的培训。它消除了冷却水的需求，降低维护和所有权成本。与能量分散XRF光谱仪相比，具有较高的灵敏度和光谱分辨率，它可以与较大的WD-XRF系统媲美。它的CSUB介绍将带来高级技术能力，从而在包括矿山尾矿，聚合物复合材料，农业废物衍生的能源和资源回收，古环摄影和古气候的催化剂的领域进行研究进步。除了其技术能力之外，该工具还将为CSUB的新研究方向铺平道路，鼓励来自不同部门的教师之间的合作项目，并促进与其他机构的研究人员的合作伙伴关系。该奖项反映了NSF的法定使命，并通过使用该基金会的知识分子优点和广泛的影响来评估NSF的法定任务，并被认为是值得的支持。
