Acquisition of elemental analyzer system and balance for C,N, and S content and isotope analyses

马尼托巴大学最近获得了加拿大创新基金会740万美元的资助，用于建立马尼托巴地区材料和表面表征设施。 作为该设施的一部分，建立了二次离子质谱实验室。 地质科学系（Fayek，霍桑，Halden，Camacho，Bekker），化学（Freund），机械工程（Cahoon，Chaturvedi），电气工程（Buchanan）和其他几位研究人员极大地受益于马尼托巴大学的西姆斯实验室。和硫循环，以及对这些地球化学信号在成岩作用、变质作用、辐解作用和向地幔俯冲过程中所经历的蚀变的理解。 最近，Fayek建立了一个CFI和RTI资助的稳定同位素实验室，因为马尼托巴大学没有稳定同位素分析仪器。 虽然这个实验室主要致力于西姆斯研究，但它也将被其他教师和学生用于稳定同位素研究。 该实验室有质谱仪和两个外围设备：热转换元素分析仪（TC-EA）和GasBench III，用于沃茨中碳酸盐和溶解无机碳的C和O同位素分析。 结合起来，这种基础设施允许某些材料的同位素表征（例如C，S，H和O）。 然而，这些装置既不适合也不能有效地同位素表征沉积物中C、N和S的还原化合物，这对PI和共同申请人的研究至关重要。 在线系统的C，N和S同位素分析的小样品具有高精度和准确性和大样品的吞吐量仍然缺乏在部门和大学。 因此，这里要求的基础设施将用于建立一个能力，目前不存在于马尼托巴大学，但必须为申请人以及其他部门的其他研究人员的前沿研究。

The University of Manitoba was recently awarded a $7.4 M from the Canada Foundation for Innovation to establish the Manitoba Regional Materials and Surface Characterization Facility.  A Secondary-ion mass spectrometry (SIMS) laboratory was established as part of this facility.  The departments of Geological Sciences (Fayek, Hawthorne, Halden, Camacho, Bekker), Chemistry (Freund), Mechanical Engineering (Cahoon, Chaturvedi), Electrical Engineering (Buchanan), and several other researchers greatly benefit from the SIMS laboratory at the University of Manitoba.A theme of this proposal is to enhance a collaborative study of biogeochemical carbon, nitrogen, and sulfur cycles on various temporal scales and in different environmental settings as well as the understanding of alteration that these biogeochemical signals experienced by diagenesis, metamorphism, radiolysis, and subduction to the mantle.  Recently, Fayek established a CFI and RTI funded stable isotope laboratory, since instrumentation for stable isotope analysis did not exist at the University of Manitoba.  Although this lab is primarily dedicated to SIMS research, it will also be used by other faculty and students for stable isotope studies.  The laboratory has the mass spectrometer with two peripherals: thermal conversion elemental analyzer (TC-EA) and GasBench III for C and O isotope analyses of carbonates and dissolved inorganic carbon in waters.  Combined, this infrastructure permits isotopic characterization (e.g. C, S, H, and O) of some materials.  However, these devices are neither appropriate nor efficient to isotopically characterize reduced compounds of C, N, and S in sediments, which are pivotal to the research of the PI and Co-applicants.  The online system for C, N, and S isotope analysis of small samples with high precision and accuracy and large sample throughput is still missing in the department and at the university.  Therefore, the infrastructure requested here will be used to establish a capability that currently does not exist at the University of Manitoba, but is necessary for cutting edge research of the applicants as well as other researchers in other departments.
