Acquisition of an Excimer Laser, Quadrupole ICPMS and Microsampler for UC Davis

0946297 Spero该奖项提供超过24个月的资金，用于获得准分子激光和四极电感耦合等离子体质谱仪（ICP-MS），用于高分辨率的古气候元素和同位素测量。所要求的配置将允许分析一系列广泛的元素和同位素。可以分析各种地质材料，仪器提供快速（0.5秒/分析）的样品吞吐量。激光器将提供超高分辨率（微米到纳米空间尺度），系统将具有最小的样本间存储问题。准确度和精密度与湿血浆ICP-MS系统相当。该系统特别适用于测量金属/钙（例如Mg/Ca、Ba/Ca、B/Ca等）。和稳定同位素（碳和氧）。研究将主要集中在古气候和古海洋学问题，但仪器将适用于许多与地球科学有关的主题。新的仪器将是一个宝贵的培训工具，研究生，博士后和优秀的本科生。该仪器将被PI和Co-PI用于研究生和本科生地球化学课程以及本科生研究项目和高级论文的教学。这种在美国独一无二的最先进的仪器将使PI，学生和博士后保持在新研究领域和技术的最前沿。该仪器将被移到最近翻修的实验室空间。PI将共同负责操作和维护。赠款收入和充值资金将用于维护仪器和支持技术人员。政府将资助大修。***

0946297 SperoThis award provides funding over 24 months to acquire an excimer laser and quadrupole inductively coupled plasma mass spectrometer (ICP-MS) for high-resolution paleoclimatological elemental and isotopic measurements. The requested configuration will allow analyzing a broad suite of elements and isotopes. Various geological materials can be analyzed and the instrument offers a rapid (0.5 sec/analysis) sample throughput. The laser will offer ultra-high resolution (micron to nanometer spatial scale), and the system will have minimal inter-sample memory problems. Accuracy and precision will be comparable to wet plasma ICP-MS systems. The system will especially useful for measuring Metal/Ca (e.g. Mg/Ca, Ba/Ca, B/Ca etc.) and stable isotopes (carbon and oxygen). Research will focus primarily on paleoclimatic and paleoceanographic questions but the instrumentation will be applicable to many geoscientific-related themes. The new instrument will be a valuable training tool for graduate students, post-docs and exceptional undergraduates. The instrument will be used for teaching by the PI and Co-PIs in graduate and undergraduate geochemistry courses and undergraduate research projects and senior theses. This state-of-the-art instrumentation, unique in the US will allow the PIs, students and postdocs to remain at the forefront of new research areas and techniques. The instrument will be moved into a recently-renovated laboratory space. The PIs will collectively be responsible for operation and maintenance. Grant income and recharge funds will be used to maintain the instrument and support a technician. The administration will fund major repairs. ***
