Acquisition of LA-ICP-MS for the Integration of Research, Research Training, and Education at Colgate University

该合同将支持采用激光烧蚀（LA）的电感耦合等离子体质谱仪（ICP-MS）的采购，这是科尔盖特大学和地区学生和教师研究和研究培训的重要组成部分。由于采用了碰撞/反应池技术，新型ICP-MS比旧型号具有更大的通用性，检测限更低，整个质谱的灵敏度更高，对复杂样品基质的耐受性更好。这些改进扩展了现有的分析能力，使以前无法获得的研究新途径成为可能。再加上激光，它将允许现场分析，新设施是来自各个科学学科的广泛项目的基石，包括火成岩和变质岩石学，矿物学，低温地球化学，古气候学，古生物学，环境，生态和固态物理学。高露洁的ICP-MS设备在研究培训中发挥着关键作用，通过独立的学生研究和广泛使用该仪器的基于项目的课程。该仪器也是高露洁几门课程的重要组成部分，包括：环境地球化学和分析、岩石学、仪器分析、生态学、酸雨高级研讨会、地球化学、环境研究和考古天文学。这些课程中有许多包含服务学习的内容，在这些课程中，学生进行具有区域环境重要性的项目，与社区团体互动，并在当地范围内发挥重要的社会作用。新仪器是一个区域性设施，对高露洁大学和地区机构的许多充满活力的研究项目至关重要，包括哈特威克学院、威尔斯学院、霍利奥克山学院和宾厄姆顿大学。这些机构的教师定期带学生到该设施工作，这提高了学生接触复杂分析仪器的机会，并鼓励学生和教师之间的区域合作。

This award will support the acquisition of an inductively coupled plasma-mass spectrometer (ICP-MS) with laser ablation (LA), an essential component of student- and faculty-based research and research training both at Colgate University and regionally. Because of collision/reaction cell technology, the new ICP-MS has greater versatility than older models, with lower detection limits, enhanced sensitivity across the mass spectrum, and better tolerance for complex sample matrices. These improvements expand existing analytical capabilities, making possible new avenues for research that were previously inaccessible. Coupled with the laser, which will permit in situ analysis, the new facility is the cornerstone for a wide range of projects from across the scientific disciplines, including igneous and metamorphic petrology, mineralogy, low temperature geochemistry, paleoclimatology, paleontology, environmental, ecological, and solid state physics. The ICP-MS facility at Colgate plays a critical role in research training, through independent student research and project-based courses that utilize the instrument extensively. The instrument is also an essential component in several courses at Colgate, including: environmental geochemistry and analysis, petrology, instrumental analysis, ecology, senior seminars on acid rain, geochemistry, environmental studies, and archaeoastronomy. Many of these courses involve service-learning components, in which students carry out projects of regional environmental importance, interacting with community groups and serving an important societal role on a local scale. The new instrumentation is a regional facility, vital to numerous vibrant research programs at Colgate and at regional institutions, including Hartwick College, Wells College, Mt. Holyoke College, and Binghamton University. Faculty from these institutions brings students to work in the facility on a regular basis, which improves their students' exposure to sophisticated analytical instrumentation and encourages regional collaborations among students and faculty.
