This award is supported by the Major Research Instrumentation (MRI) and the Chemistry Research Instrumentation (CRIF) Programs. Professor Justin Miller-Schulze from California State Sacramento (University Enterprises Inc.) and colleagues Thomas Landerholm and Amelia Vankeuren have acquired a high pressure liquid chromatograph mass spectrometer (HPLC-MS.) In general, mass spectrometry (MS) is one of the key analytical methods used to identify and study small quantities of chemical species embedded in complex samples. In a typical experiment, the components move into a mass spectrometer where they are ionized and the ions' masses masses are measured. This highly sensitive technique allows the determination of the structure of molecules in a complex mixture. An instrument with a liquid chromatograph separates mixtures of compounds before they reach the mass spectrometer. This acquisition strengthens the research infrastructure at the university and regional area. The instrument broadens participation by involving diverse groups of students in research. It also provides training opportunities to many undergraduate students through a variety of programs such as Sacramento State's Sustainable Interdisciplinary Research to Inspire Undergraduate Success (SIRIUS) program, whose goal is to provide undergraduates with authentic research experiences. This program involves students from the Biological Sciences, Chemistry, Geology and Environmental Studies. It includes a Course-based Undergraduate Research Experiences (CUREs) centered on the American River ecosystem as a central theme.The mass spectrometer enhances research and education at all levels. It especially benefits research efforts investigating sources of adverse surface water quality using chemicals of emerging concern. The mass spectrometer also aids in the determination of the fate and transport of groundwater contaminants in mixtures related to oil and gas production.

该奖项由主要研究仪器（MRI）和化学研究仪器（CRIF）计划支持。来自加州州萨克拉门托的Justin Miller-Schulze教授（大学企业公司）和同事托马斯兰德霍尔姆和阿米莉亚Vankeuren已经获得了高压液相色谱质谱仪（HPLC-MS）。一般来说，质谱（MS）是用于识别和研究复杂样品中嵌入的少量化学物质的关键分析方法之一。在一个典型的实验中，这些成分进入质谱仪，在那里它们被电离，并测量离子的质量。这种高灵敏度的技术可以确定复杂混合物中分子的结构。带有液相色谱仪的仪器在化合物到达质谱仪之前将其分离。此次收购加强了大学和地区的研究基础设施。该工具通过让不同的学生群体参与研究，扩大了参与。它还通过各种计划为许多本科生提供培训机会，例如萨克拉门托州立大学的可持续跨学科研究以确保本科生成功（SIRIUS）计划，其目标是为本科生提供真实的研究经验。该计划涉及生物科学，化学，地质学和环境研究的学生。它包括以美国河流生态系统为中心的基于课程的本科生研究经验（CURES）作为中心主题。质谱仪增强了各级的研究和教育。它特别有利于使用新出现的令人关切的化学品调查不利地表水质量来源的研究工作。质谱仪还有助于确定与石油和天然气生产有关的混合物中地下水污染物的命运和迁移。
