SIMS standards for lithium in carbonaceous matrices

This dataset is for the manuscript 'SIMS standards for lithium in carbonaceous matrices' submitted to the journal Geostandards and Geoanalytical Research. The data includes SIMS depth profile results of Li implants into polymers, carbon glass and NIST 612 silicate glass standards. The goal of this research was to evaluate potential matrix effects for Li in kerogen. Because kerogen is not homogenous, polymers of similar compositions to kerogen were created via Li ion implantation to serve as standards for kerogen. We were particularly interested in how varying compositions of C, H and O may affect the content and isotope calibration of Li in kerogen. The data included contain individual measurements of SIMS depth profiles as well as the calculations for the determination of Li content calibration factors, sputter yields, useful ion yields, etc.

本数据集对应投稿于"Geostandards and Geoanalytical Research"期刊的学术手稿《碳质基质中锂的二次离子质谱（SIMS）标准》。数据集涵盖了锂（Li）注入聚合物、碳玻璃及NIST 612硅酸盐玻璃标准物质后的二次离子质谱深度剖面测试结果。本研究旨在评估干酪根中锂的潜在基质效应：由于干酪根并非均质物质，研究团队通过锂（Li）离子注入制备了与干酪根组成相似的聚合物，以作为干酪根分析的标准物质。本次研究重点关注碳（C）、氢（H）及氧（O）的组成变化如何影响干酪根中锂的含量及其同位素校准。本数据集收录的数据包含二次离子质谱深度剖面的单次测试结果，以及用于测定锂含量校准因子、溅射产额、有效离子产额等相关参数的计算数据。
