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.

该奖项得到了主要的研究工具（MRI）和化学研究工具（CRIF）计划的支持。来自加利福尼亚州萨克拉曼多（University Enterprises Inc.）和同事托马斯·兰德霍尔姆（Thomas Landerholm）和阿米莉亚·范基伦（Amelia vankeuren）的贾斯汀·米勒·舒尔兹（Justin Miller-Schulze）教授已经获得了高压液态色谱质谱仪（HPLC-MS。），总体上，质谱法（MS）是用于识别和研究小量子量的关键分析方法之一。在典型的实验中，组件移至质谱仪中，并测量了离子质量的质量。这种高度敏感的技术允许确定复杂混合物中分子的结构。具有液相色谱仪的仪器将化合物的混合物分开，然后才能到达质谱仪。这项收购加强了大学和地区地区的研究基础设施。该仪器通过参与研究的不同群体来扩大参与。它还通过各种计划，例如萨克拉曼多州的可持续跨学科研究，以激发本科生成功（Sirius）计划，为许多本科生提供培训机会，其目标是为大学生提供真实的研究经验。该计划涉及来自生物科学，化学，地质和环境研究的学生。它包括一个基于课程的本科研究经验（治疗疗法），该研究经验以美国河流生态系统为中心。它特别有利于研究工作的研究努力，利用新兴关注的化学物质来调查不利地表水质的来源。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运输。
