This award will provide funding to Western Washington University (WWU) to upgrade an existing but aging inductively-coupled-plasma-mass spectrometer and associated 213 nm laser (LA-ICP-MS) to a significantly-improved LA-ICP-MS system with an advanced 193 nm laser. This instrument will add exciting new opportunities for faculty research, thesis research of undergraduate and graduate students, and course-based research at a dominantly undergraduate institution that has an outstanding record of well-cited publications involving students. Of the 5 co-principal investigators and 2 senior personnel on this grant, 5 are early career researchers within the first four years of their appointment at WWU and this instrument will significantly enhance their research productivity. The new instrument will support grant-funded research with students that covers topics as broad-ranging as utilization of chemical signatures in volcanic glasses/crystals to discern eruption processes, characterization of deep-Earth materials, timescales and rates of ancient subduction zone processes, transport of plastic nanoparticles in the environment, geochemical signatures in biogenic carbonates as recorders of past climate, ore deposit genesis, abundances of particulate matter pollution, and toxicity of metals in marine and terrestrial systems. The LA-ICP-MS will continue to be used to promote research and education partnerships via outreach to pre-college students, nearby community colleges and entering WWU freshman with an interest in STEM, but this grant specifically develops new collaborations with nearby Whatcom Community College (WCC) and WWU Geology and Environmental Sciences departments to develop course-based undergraduate research experiences and paid summer research experiences for undergraduates.The ICP-MS and associated laser upgrade will improve and expand the current high quality and broad scope of research, including NSF-funded projects, conducted within the Geology Department and the College. Replacing the current unsupported instrument is essential to ensure the uninterrupted functioning of our facility, and the new Agilent 7900 ICP-MS will provide significantly improved detection limits, count sensitivity, plasma stability, and handling of laser particles. A coupled laser, the RESOlution-SE system, will provide a reliable introductory system for non-aqueous samples, which historically make up half of the total samples analyzed at WWU. Specifically, this system will expand the range of materials that can be analyzed (in terms of both composition and size), minimize fractionation, and significantly enhance precision, detection limits, and sample navigation and programming. It will also provide for an additional LIBS detector permitting periodic table masses at a weight percent to ppm range. These upgrades to the ICP-MS and laser ablation system are necessary for researchers working with nanoparticles and toxins, translucent solid materials (e.g., minerals such as quartz and plagioclase), trace element concentrations below 10 μg/g, small solid samples (100 μm diameter), large solid samples that do not fit in the sample chamber, and more. The intuitive designs and excellent coupling of the Agilent 7900 and RESOlution-SE operational programs will also improve user accessibility and training (dominantly students).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.

该奖项将为西部华盛顿大学（WWU）提供资金，以升级现有但老化的电感耦合 - 质量质量光谱仪，并将213 nm激光器（LA-ICP-MS）与高级193 nm激光器相关的LA-ICP-MS系统相关联。该乐器将为教师研究，本科生和研究生的论文研究以及在一个主要的本科机构的基于课程的研究中增加令人兴奋的新机会，该学院具有杰出的涉及学生的出色记录。在这笔拨款的5名联合主持调查员和2名高级人员中，有5名是在WWU任命的前四年内的早期职业研究人员，该工具将大大增强其研究产品。新仪器将支持与学生进行赠款资助的研究，这些研究涵盖了宽范围的范围，作为在火山眼镜/晶体中使用化学特征的利用，以辨别喷发过程，对深地球材料的表征，古代俯冲带过程的表征和速率速率和速率的速率，在环境中的塑料纳米颗粒的运输，在环境中的造成量的造成量的造成量的造成量的造成量，以弥补的造成量，以弥补生物的造成频率，以弥补生物量的频率，以弥补生物的探索，涉及较高的碳量。和金属在海洋和陆地系统中的毒性。 LA-ICP-MS将继续用于促进研究和教育伙伴关系，通过向预科学生提供宣传，靠近社区大学，并进入对STEM感兴趣的WWU大一新生，但该赠款专门与Whatcom Community College（WCC）（WCC）和WWU地质学和环境研究经验的近乎差不多进行了新的合作，并培养了基于课程的研究生，并培养了ICEP ICP的经验，并培养了ICP的研究人员，并培养了ICP的研究人员，并培养了ICP的研究人员，并培养了ICPRADS ICP的研究人员，并培养了ICER的研究生，并培养了ICP的研究人员，并培养了ICP的培训。激光升级将改善和扩大当前高质量和广泛的研究范围，包括在地质系和学院内进行的NSF资助的项目。更换电流的无支撑仪器对于确保我们设施的不间断功能至关重要，而新的Agilent 7900 ICP-MS将提供显着改善的检测极限，计数灵敏度，等离子体稳定性以及激光颗粒的处理。耦合激光器（分辨率-SE系统）将为非水样品提供可靠的介绍系统，从历史上看，该系统占WWU分析的总样品的一半。具体而言，该系统将扩展可以分析的材料范围（以组成和大小而言），最小化分级，并显着提高精度，检测极限以及样本导航和编程。它还将提供额外的LIB探测器，允许重量百分比至ppm范围的元素表质量。这些升级到ICP-MS和激光消融系统对于使用纳米颗粒和毒素，半透明的固体材料（例如，矿物质，例如石英和斜长石），低于10μg/g的痕量元素浓度，必不可少直观的设计和Agilent 7900和解决方案运营计划的出色耦合也将改善用户的可访问性和培训（主要是学生）。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的评估标准来评估通过评估而被认为是宝贵的。
