MRI: Acquisition of a Raman and laser-induced breakdown spectroscopy (LIBS) microscope for interdisciplinary research and research training at Seattle University

有了这个主要研究仪器（MRI）计划的奖项，来自西雅图大学的Christopher Stipe教授和同事Ryan McLaughlin，Frank Shih，凯瑟琳库德和J.韦斯利将获得集成的拉曼和激光诱导击穿光谱（LIBS）显微镜。该提案旨在加强各级的研究、培训和教育，特别是在以下领域：（a）地质材料的识别和量化;（B）沉积物指纹，以支持沉积物来源的确定;（c）轻合金和生物材料的定性;（d）为环境健康监测分析地下采煤颗粒物;以及（e）可持续水泥基材料的开发。Raman-LIBS显微镜在样品表面的空间上快速获取元素和分子化学信息。在拉曼模式下，仪器提供关于样品的化学组成、结构、相和多晶型的信息;在LIBS模式下，仪器提供元素组成。因此，可以获得大量样品的化学绘图和深度剖析。该仪器将用于该机构三个部门的教师和学生的研究。它还将用于与伯克自然历史和文化博物馆的合作研究，研究美国原住民艺术中使用的颜料，并用于当地高中STEM学生学习化学和法医学的暑期沉浸课程。

With this award from the Major Research Instrumentation (MRI) program, Professor Christopher Stipe from Seattle University and colleagues Ryan McLaughlin, Frank Shih, Katherine Kuder and J. Wesley will acquire an integrated Raman and laser-induced breakdown spectroscopy (LIBS) microscope. The proposal is aimed at enhancing research training and education at all levels, especially in areas such as (a) identification and quantification of geological materials; (b) sediment fingerprinting in support of sediment source determination; (c) characterization of light alloys and biomaterials; (d) analysis of underground coal mining particulate matter for environmental health monitoring; and (e) development of sustainable cement-based materials.A Raman-LIBS microscope rapidly acquires both elemental and molecular chemical information spatially across a sample surface. In Raman-mode, the instrument provides information regarding a sample's chemical composition, structure, phase, and polymorphism; in LIBS-mode, the instrument provides elemental composition. Thus chemical mapping and depth profiling of a wide array of samples can be obtained. The instrument will be used in research by faculty and students in three departments at the institution. It also will be employed in a collaborative study with the Burke Museum of Natural History and Culture studying pigments used in Native American art and in a summer immersion program for STEM students from a local high school to learn chemistry and forensic science.
