Acquisition of a Fourier transform infrared spectrometer to map water in the Earth's mantle

Peslier这项提案寻求资金，以获得带有显微镜附件的傅里叶变换红外光谱仪(FTIR)。这项收购将允许显微光谱学在中红外、近红外和紫外可见光谱范围内，空间分辨率接近8微米。需要一台配备Continuum XL红外显微镜的Thermo-Nicolet 6700 FT-IR光谱仪。新的收购将设在月球和行星研究所(LPI)。该仪器将能够分析不同地幔区域(海洋与大陆、克拉通与非克拉通等)地质标本中的水变化和含量。具体的应用是：1)绘制单个矿物样品的OH和H2O振动区；2)绘制单个颗粒的OH吸收强度图；3)分析含水率低于0.3ppm的地幔矿物中的氢；4)识别玻璃和矿物基质中不同的氢物种；5)生成上地幔区域的3D水图。仪器将由私人助理管理，他们将提供培训并确保最佳使用。Pi Peslier是NASA-Johnson空间中心天体材料和空间研究部的电子微探针经理，也是LPI的客座科学家，负责电子微探针管理和50%的研究。FTIR将设在LPI，以允许来自其他机构的合作者以及外国国民访问仪器。该仪器将提供给从事水研究的研究人员吗？对地球和地外样品的岩石测量。除两个个人投资促进机构外，还有六个主要用户将在各种项目中使用该仪器。休斯顿大学市中心分校的研究人员？加尔维斯顿、德克萨斯A&M、休斯顿理工学院、德克萨斯南部和其他地方将可以使用仪器。*

0743377Peslier This proposal seeks funding to acquire a Fourier transform infrared spectrometer (FTIR) with a microscope attachment. This acquisition will allow microspectroscopy at the mid-IR, near-IR and UV-visible spectral range with spatial resolution approaching 8 µm. Requested is a Thermo-Nicolet 6700 FT-IR spectrometer with a Continuum XL IR microscope. The new acquisition will be housed at the Lunar and Planetary Institute (LPI). This instrument will enable the analysis of water variations and content in geologic specimens from various mantle domains (oceanic versus continental, cratonic versus non-cratonic, etc). Specific applications are to 1) map OH and H2O vibrational regions on individual mineral samples, 2) map OH absorbance intensity on single grains, 3) analyze hydrogen in mantle minerals with water content less than 0.3 ppm, 4) identify different hydrogen species in glass and mineral matrices, and 5) generate 3D water maps in upper mantle regions. The instrument will be managed by the PIs who will provide training and ensure optimal usage. PI Peslier is the electron microprobe manager at the Astromaterials and Space Research division at NASA-Johnson Space Center and a visiting scientist at LPI with 50% labor for electron microprobe management and 50% research. The FTIR will be located at LPI to allow collaborators from other institutions as well as foreign nationals access to the instrumentation. The instrument will be made available to researchers engaged in water ? rock measurements on terrestrial and extraterrestrial samples. Six major users in addition to the two PIs will use the instrument for various projects. Researchers from University of Houston Downtown, UH - Clear Lake, UH ? Galveston, Texas A&M, Houston College of Sciences, Texas Southern and others will have instrument access.***
