Acquisition of an Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) for the Enhancement of Interdisciplinary Research and Research Training

这项来自学术研究基础设施(ARI)计划的奖项将帮助劳伦斯大学化学系获得一台电感耦合等离子体质谱仪(ICP-MS)。该设备将加强以下领域的研究：(1)加拉帕戈斯岛链的演化(2)威斯康星州中东部温尼高湖盆地的第四纪晚期历史(3)最近对温尼贝戈湖盆地的人为影响(4)调查半导体Ge1-(X)Snx的电子和振动能带结构，以及(5)淡水和海洋环境中浮游动物营养物质的供应。电感耦合等离子体质谱(ICP-MS)是一种利用流动的导电气体中感应磁场产生的高温放电进行高精度、定量的多元素分析的分析技术。它被用于环境科学、材料科学和地球化学等跨学科领域，以获得高质量的元素分析。

This award from the Academic Research Infrastructure (ARI) Program will assist the Department of Chemistry at Lawrence University acquire a inductively coupled plasma-mass spectrometer (ICP-MS). This equipment will enhance research in a number of areas including the following: (1) evolution of the Galapagos Island Chain (2) late quaternary history of the Lake Winnegao Basin East-Central Wisconsin (3) recent anthropogenic effects on the Lake Winnebago Basin (4) investigation of electronic and vibrational band structure of the semiconductor Ge1-(x)Snx, and (5) zooplankton nutrient supplies in freshwater and marine environments. Inductively coupled plasma-mass spectrometry (ICP-MS) is an analytical technique that uses a high temperature discharge generated by inducing a magnetic field in a flowing conducting gas to determine with high precision, quantitative multi-elemental analysis. It is used in interdisciplinary fields including environmental science, material science and geochemistry for high quality elemental analysis.
