Acquisition of an Automated Carbonate Preparation Device (Isotope Ratio Mass Spectrometry) for Studies of Paleoceanography, Geochemistry & Marine Biology

该提案要求提供资金，用于购买一台自动碳酸盐制备装置，以连接圣巴巴拉加州大学新的Finnigan-MAT Delta E光稳定同位素质谱仪。ACPD将使大量碳酸盐样品的氧和碳同位素组成分析非常迅速，有效和高精度。该实验室将用于氧和碳同位素研究，应用于古海洋学/古气候学/地层学;沉积物成岩;软体动物的古生态学;寒武纪/前寒武纪边界的叠层石地球化学和同位素变化;碳酸盐岩，海洋生物学和碳酸盐物质的其他研究。ACPD已被Finnigan-MAT借出至1988年12月31日，届时必须购买或归还。我们需要确信该系统有效，因此进行了与各种标准相关的密集校准和精度测试。这些都是高度令人满意的，我们已经广泛使用的设施，这将是至关重要的，我们未来提出的研究计划。

This proposal requests funds to purchase an Automated Carbonate Preparation Device (ACPD) for attachment to a new Finnigan-MAT Delta E light stable isotope mass spectrometer at the University of California, Santa Barbara. The ACPD will enable large numbers of carbonate samples to be analyzed for oxygen and carbon isotopic composition very rapidly, efficiently and with high precision. The labortory is to be used for oxygen and carbon isotopic studies as applied to paleoceanography/paleoclimatology/ stratigraphy; sediment diagensis; paleoecology of mollusca; stromatolite geochemistry and isotopic changes at the Cambrian/ Precambrian boundary; carbonatites, marine biology and other studies on carbonate materials. The ACPD has been loaned by Finnigan-MAT until December 31,1988, at which time it must be purchased or returned. We needed to be convinced that this system works and, thus, conducted intensive calibration and precision tests related to a wide range of standards. These have been highy satisfactory and we are already making extensive use of the facility which will be crucial for our future proposed research programs.
