MRI: Acquisition of a High-Resolution Double-Focusing Magnetic Sector-Field Mass Spectrometer (HR-ICP-MS) for Paleoclimate and Biogeochemical Research

提供资金用于购置一台单收集器高分辨率双聚焦磁扇形场质谱仪，用于古气候和地球化学研究。质谱仪将有助于高精度测量无机和有机溶液基质中的元素浓度和同位素比率，用于广泛的自然沃茨和地球化学应用。 这些应用包括洞穴沉积物的高分辨率古气候记录、南极和格陵兰冰芯的硫同位素变化、植被和土壤的碳循环和地球化学。更广泛的影响包括使用质谱仪解决气候变化和不同时间尺度上元素循环的基础研究问题，以及帮助一位有前途的女科学家在职业生涯早期进一步发展。

Funding is provided to acquire a single-collector high-resolution double-focusing magnetic sector-field mass spectrometer for paleoclimate and biogeochemical research. The mass spectrometer will help enable high-precision measurement of elemental concentrations and isotope ratios in inorganic and organic solution matrices for a wide range of natural waters and geochemical applications. Such applications include high resolution paleoclimate records from speleothems, sulfur isotope variability in Antarctic and Greenland ice cores, and carbon cycling and biogeochemistry of vegetation and soils.The broader impacts involve using the mass spectrometer to address fundamental research question in climate change and elemental cycling over various time scales as well as helping to further the career of a promising female scientist early in her career.
