一种原位微区Mg同位素测定方法相关专利数据集

本项目是一种原位微区Mg同位素测定方法相关专利数据集，在中国地质大学（武汉）地质过程与矿产资源国家重点实验室获得。使用257nm飞秒激光和Neptune Plus MC-ICP-MS进行原位Mg同位素分析。采用样品-标样间插法进行仪器质量歧视校正，BHVO-2G被用作外部标样，其他国际标样作为未知样品进行了反复分析，以评估湿等离子体条件下非基体匹配校正的可靠性。该数据可以作为硅酸盐矿物激光原位Mg同位素测试的质量监控。This dataset is associated with a patented in-situ micro-scale Mg isotope determination method, and was collected at the State Key Laboratory of Geological Processes and Mineral Resources, China University of Geosciences (Wuhan). In-situ Mg isotope analysis was performed using a 257 nm femtosecond laser and a Neptune Plus MC-ICP-MS. Instrumental mass discrimination was corrected using the sample-standard bracketing method. BHVO-2G was adopted as the external standard, while other international standards were repeatedly analyzed as unknown samples to assess the reliability of non-matrix-matched correction under wet plasma conditions. This dataset can serve as a quality control tool for laser ablation in-situ Mg isotope testing of silicate minerals.
