0214265SchimmelmannThis grant supports the acquisition of a gas source stable isotope ratio mass spectrometer configured for continuous flow operation (CF-irmMS) and with associated sample introduction peripherals that will allow for the analysis of multiple stable isotopic ratios in a wide range of natural materials including, organic matter, carbonates, hydrous minerals and water. Specific sample inlet devices will include an elemental analyzer (EA), a gas chromatograph (GC), and an automated carbonate preparation device. The new CF-irmMS will complement two existing stable isotope ratio mass spectrometers(both late model Finnegan MAT 252s) in the Geological Sciences department at Indiana University. One was recently funded by the EAR/IF program (NSF-9726264) to co-PI Ed Ripley and is dedicated to the analysis of the isotopic composition of sulfide ores and the other is somewhat older (vintage 1991) and is dedicated to analysis of carbonate carbon. The new instrument will greatly expand the current isotopic capabilities of this already well equipped department by adding the ability to make high precision isotopic analyses of hydrogen/deuterium (H/D) ratios in extremely small samples of organic matter and natural waters with high throughput. The requested peripheral devices will also allow for investigation of the stable isotopic signatures of individual compounds of organic materials. The instrument will support the research efforts of numerous IU faculty including Arndt Schimmelmann, Lisa Pratt, Ed Ripley, Peter Sauer and Jeff White and their students for research spanning the fields of paleoclimatology, oceanography, ecology and hydrology. The addition of a CF-irmMS to this lab will undoubtedly serve to further the attraction of this facility to a number of active geoscientists and will likely lead to future productive collaborations with these IU scientists and their students. ***

0214265schimmelmannththis Grant支持采集用于连续流动（CF-ERMMS）的气源稳定同位素比率质谱仪，并通过相关的样品简介外围设备，可以分析在包括自然物质的各种自然材料中，包括有机物，水和水，水和水的多种材料中的多种稳定同位素比。 特定的样品入口设备将包括元素分析仪（EA），气相色谱仪（GC）和一个自动化的碳酸盐准备装置。 新的CF-IRMM将补充印第安纳大学地质科学系的两个现有稳定的同位素比率质谱仪（均为晚期Finnegan MAT 252S）。 一个最近由EAR/IF程序（NSF-9726264）资助，以共同介绍Ripley，并致力于分析硫化物矿石的同位素组成，而另一个则有些较早（Vintage 1991），并致力于分析碳酸盐碳。 新仪器将通过增加在极少数有机物和具有高吞吐量的天然水样本中对氢/氘（H/D）比率进行高精度的同位素分析的能力，从而大大扩展了该已经设备齐全的部门的当前同位素能力。 所需的外围设备还将允许研究有机材料各个化合物的稳定同位素特征。该工具将支持包括Arndt Schimmelmann，Lisa Pratt，Ed Ripley，Peter Sauer和Jeff White在内的众多IU教师的研究工作。 在该实验室中增加了CF-IRMMS将无疑将该设施吸引到许多活跃的地球科学家中，并可能导致与这些IU科学家及其学生的未来生产性合作。 ***
