Development of Analytical Techniques for ICP-MS and LA-ICP- MS

该合同提供资金用于购买仪器部件，用于提高康奈尔大学地质科学系安装的电感耦合等离子质谱仪(ICPMS)系统的分析能力(提高灵敏度和减少质量干扰)。PI和研究小组还将开发用于电感耦合等离子体质谱仪的激光消融源。激光烧蚀采样的巨大潜力在于其具有空间分辨率的原位分析能力，但由于其适用于复杂的地质样品目标，其应用还需要很大的发展。该项目将开发具体的分析技术，对地壳和地幔矿物中的微量元素进行微量分析。

This award provides funding for the acquisition of instrument components that will serve to upgrade the analytical capabilities (improved sensitivity and decreased mass interferences from oxides) of an inductively coupled plasma-mass spectrometer (ICP-MS) system installed in the Department of Geological Sciences at Cornell University. The PI and research group will also develop the use of a laser ablation source for the ICP-MS. The great promise of laser ablation sampling is its capability for in situ analysis with spatial resolution, but the application still requires much development as it applies to complex geological sample targets. The project will develop specific analytical techniques for microanalysis of trace elements in crustal and mantle minerals.
