Geology (42) The ICP-MS will be used, in conjunction with our existing ion chromatograph, in the chemical analyses of natural samples in both regular courses and student-research projects. In our shared analytical facility, course-related exercises and senior research work are implemented across all four years of the curriculum in the Departments of Geology (5 courses), Chemistry (2 courses), Biology (2 courses), and Civil Engineering (4 courses). The facility will also be utilized in the interdisciplinary Environmental Studies Program. The ICP-MS is being used as a research tool to provide experiences for all levels of students: 1) Introductory level students focus on exercises adapted from selected components of watershed investigation projects implemented elsewhere (e.g., Tonn and Whitman, 1996, Colby College). Students collect samples that are analyzed outside of class. In class, data are plotted and discussed in terms of conceptual models to determine how the samples attained their compositions. 2) Intermediate level students complete more advanced exercises adapted from a variety of projects elsewhere (e.g., Ousey, 1993, Pennsylvania State University; de Wet, 1994, Franklin and Marshall College; Tonn and Whitman, 1996, Colby College; Lee, 1998, Auburn University; Dunnivant et al., 1999, Hartwick College). The students collect, prepare, and analyze samples in largely inquiry-driven, open-ended projects. The exercises allow implementation of experimental design, practical sample collection and preparation techniques, and sampling and analytical strategies. As final products, students prepare substantial written reports that include data presentation and interpretation components. 3) Senior level students use the ICP-MS in directed research projects (theses) adapted from their research advisor's own ongoing scholarship, or in projects largely of the student's own design. These students collect, prepare, and analyze samples, and are involved in planning and implementing analysis and sampling strategies and data interpretation. Many theses result in formal publications and/or presentations at scientific conferences.

地质学(42)在常规课程和学生研究项目中，电感耦合等离子体质谱仪将与我们现有的离子色谱仪一起用于天然样品的化学分析。在我们共享的分析设施中，与课程相关的练习和高级研究工作在地质(5门课程)、化学(2门课程)、生物学(2门课程)和土木工程(4门课程)的所有四年课程中进行。该设施还将用于跨学科环境研究计划。ICPMS正被用作一种研究工具，为所有级别的学生提供经验：1)入门级学生专注于根据其他地方实施的分水岭调查项目的选定组成部分改编的练习(例如，Tonn and Whitman，1996，Colby College)。学生收集样本，并在课外进行分析。在课堂上，根据概念模型绘制和讨论数据，以确定样本是如何组成的。2)中级水平的学生完成了从其他地方的各种项目中改编的更高级的练习(例如，Ousey，1993，宾夕法尼亚州立大学；De Wet，1994，富兰克林和马歇尔学院；Tonn and Whitman，1996，Colby学院；Lee，1998，奥本大学；Dunnivant等人，1999，Hartwick学院)。学生们在很大程度上是由调查驱动的开放式项目中收集、准备和分析样本。这些练习允许实施实验设计、实用的样品收集和制备技术以及采样和分析战略。作为最终产品，学生要准备大量的书面报告，其中包括数据展示和解释部分。3)高年级学生在指导研究项目(论文)中使用电感耦合等离子体质谱仪，这些项目改编自他们的研究导师自己正在进行的奖学金，或者主要是学生自己设计的项目。这些学生收集、准备和分析样本，并参与计划和实施分析和抽样策略以及数据解释。许多论文形成了正式出版物和/或在科学会议上发表的报告。
