不同流程和地质标样的Zn同位素数据

数据内容：由于不同实验室及不同类型标样的锌同位素数据存在偏差，数据难以直接对比。本数据集提供了基于改进化学纯化流程后测得的合成溶液（IRMM-3702、IPG AAS Zn、GSB Zn）和多类型标样（玄武岩、安山岩、碳酸岩、花岗岩、沉积物、土壤）的锌同位素值，以及实验室对IRMM-3702、IPG AAS Zn及GSB Zn的长期分析精度结果。
数据来源：中国地质大学（北京）同位素实验室。
加工方式：将筛选好的样品经过化学纯化流程处理后，使用多接收电感耦合等离子体质谱仪（MC-ICP-MS）进行数据采集。
数据质量：每个样品重复测试2~230次，采用样品-标液交叉法和内标法进行质量歧视校正，误差以2SD表示。
应用价值：本数据提供了一种简便、通用性强的锌同位素纯化流程，并为不同实验室和不同标样的数据对比提供了基准参考值。

Data Content: Zinc isotope data from different laboratories and various reference materials have inconsistencies, making direct comparison infeasible. This dataset provides zinc isotope values of synthetic solutions (IRMM-3702, IPG AAS Zn, GSB Zn) measured via an improved chemical purification procedure, as well as multiple types of reference materials including basalt, andesite, carbonatite, granite, sediment, and soil. It also includes the long-term analytical precision results of IRMM-3702, IPG AAS Zn and GSB Zn obtained by the laboratory.
Data Source: Isotope Laboratory, China University of Geosciences (Beijing).
Processing Method: Selected samples were processed through a chemical purification workflow, followed by data acquisition using a Multi-collector Inductively Coupled Plasma Mass Spectrometry (MC-ICP-MS).
Data Quality: Each sample was repeatedly tested 2 to 230 times. Mass bias correction was performed using both the sample-standard bracketing method and internal standard method, with errors expressed as 2 standard deviations (2SD).
Application Value: This dataset provides a simple and versatile zinc isotope purification procedure, and offers benchmark reference values for data comparison across different laboratories and various reference materials.
