Support from the National Science Foundation will be used to acquire a time-of-flight inductively coupled plasma-mass spectrometer (TOF-ICP-MS), which will be added to a core of analytical instruments being assembled by a collaborative team of faculty in the College of Liberal Arts (CLA) and the College of Natural Sciences and Mathematics (CNSM) at California State University Long Beach (CSULB). Analytical instruments funded by NSF MRI grants within this core facility operated by our research group include a quadrupole ICP-MS, a laser ablation system, an environmental SEM with attached EDX and WDS, and a low-mass stable isotope mass-spectrometer. A thermoluminescence/optical luminescence measurement system, funded by alternate sources, will be added in the near future. The TOF-ICP-MS complements the existing quadrupole ICP-MS by offering superior transient-signal analysis (ideal for laser-ablation sample introduction) and superior isotope ratio precision. These advantages will be exploited in a variety of archaeological, geological, and biological research applications. In archaeology, the TOF-ICP-MS instrument coupled to a laser ablation system will enhance research into artifact provenance by improving macro- and micro-level chemical characterization and by making it possible to combine elemental and isotope-ratio characterization. In geology, the new instrument will be used in investigations of paleoceanographic and tectonic history of the Neogene and Quaternary California Margin. In biology, the high resolution isotopic ratioing and simultaneous, high acquisition rate time-resolved analysis that can only be provided by a TOF-ICP-MS will enhance ongoing investigations of how organisms balance their metabolic requirements for essential metals against the bioavailability of these metals in the environment. The broader impact of this instrument acquisition will be to enhance the interdisciplinary education and research environment at CSULB. CSULB, a non-Ph.D. granting institution, is the second-largest university in California, and, in 2000, it was designated a MSI (minority-serving institution) by the U.S. Department of Education. The PIs on this project are members of a collaborative team of faculty in the CLA and CNSM who are promoting interdisciplinary research and instruction in what can broadly be labeled "historical sciences." Minimally, historical sciences include geology, biology, geography, and archaeology, but we prefer to define the field not by the existing disciplines it subsumes but rather as any scientific investigation of historical and evolutionary phenomena, be they geological, biological, or cultural. One way we are promoting interdisciplinary historical science research and education is by supporting use of analytical instruments, including the new TOF-ICP-MS, by a variety of student and faculty researchers. Locally, students who major in archaeology, geology, biology, and other sciences, many of whom are from underrepresented groups, will receive hands-on experience with the state-of-the-art instrumentation in our laboratories. We also plan to extend an existing short-term visitor program that will bring collaborating researchers of any academic rank, from undergraduate to senior faculty, to CSULB to use the TOF-ICP-MS and other instruments. The overall goal we are pursuing through this instrument acquisition and other ongoing initiatives is creation of an interdisciplinary center that will be a resource for CSULB, the California State University System, and the broader community of scientists investigating historical phenomena.

国家科学基金会的支持将用于获得飞行时间的电感耦合等离子体质量光谱仪（TOF-ICP-MS），将添加到由自由主义艺术学院（CLA）和自然科学和数学学院（CARICACENSMASM）（CARICACSMAL）（CARICACHIA）（CARICACHIA）（CARICACHIA）（CCARCAL）（CCARIADIA）组成的分析仪器核心。由NSF MRI赠款资助的分析工具由我们的研究小组运营的核心设施中，包括四极ICP-MS，激光消融系统，带有EDX和WDS的环境SEM以及低质量的同位素质量谱仪。在不久的将来，将添加由替代来源资助的热发光/光发光测量系统。 TOF-ICP-MS通过提供优质的瞬态信号分析（非常适合激光燃料样品引入）和出色的同位素比精度来补充现有的四极ICP-MS。这些优势将在各种考古，地质和生物学研究应用中利用。在考古学中，与激光消融系统耦合的TOF-ICP-MS仪器将通过改善宏观和微观化学表征以及结合元素和同位素比例表征来增强对伪影来源的研究。在地质学中，新仪器将用于对新近纪和第四纪边缘的古文化和构造历史的调查。在生物学中，高分辨率的同位素比和同时的高采集率时间分辨分析只能由TOF-ICP-MS提供，这将增强对生物体如何平衡其代谢金属对这些金属在环境中生物可利用性的代谢需求的持续研究。该工具获取的更广泛的影响是增强CSULB的跨学科教育和研究环境。 csulb，非ph.d。 Grant Institution是加利福尼亚的第二大大学，2000年，它被美国教育部指定为MSI（少数派服务机构）。该项目的PI是CLA和CNSM的合作团队的成员，他们正在促进跨学科研究和教学，以广泛标记为“历史科学”。最少的历史科学包括地质，生物学，地理学和考古学，但我们更愿意通过现有学科所包含的现有学科来定义该领域，而是对历史和进化现象的任何科学研究，无论是地质，生物学或文化。我们促进跨学科历史科学研究和教育的一种方式是支持各种学生和教职员工研究人员使用分析工具，包括新的TOF-ICP-MS。在当地，考古，地质，生物学和其他科学专业的学生（其中许多来自代表性不足的群体）将获得我们实验室中最先进的仪器的动手经验。我们还计划扩展一项现有的短期访问者计划，该计划将带来任何学术等级的合作研究人员，从本科到高级教职员工，再到CSULB使用TOF-ICP-MS和其他工具。我们通过此工具的收购和其他持续的计划实现的总体目标是创建一个跨学科中心，该中心将成为CSULB，加利福尼亚州立大学系统和更广泛的科学家社区，研究历史现象。
