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.

本数据集旨在支持提交至《地学标准与地球分析研究》期刊的论文《SIMS 标准在碳质基体中锂的应用》。数据集涵盖了锂在聚合物、碳玻璃以及美国国家标准与技术研究院（NIST）612 型硅酸盐玻璃标准样品中的离子束注入深度分布的 SIMS 测试结果。研究旨在评估锂在干酪根中的基质效应。鉴于干酪根的非均质性，通过锂离子注入技术在结构组成与干酪根相似的聚合物中制造了标准样品，以作为干酪根的标准。研究重点在于碳、氢和氧的组成变化如何影响干酪根中锂的含量及其同位素校准。数据集包括 SIMS 深度分布的个体测量结果，以及确定锂含量校准因子、溅射产额、有效离子产额等计算结果。
