2026-01-16 Trace U/Th in Copper by ICP-MS: Sample/Blank Results and k-Coefficient Dataset doi:10.57760/sciencedb.hjs.00601 en This dataset supports the manuscript “Trace Uranium and Thorium Determination in Copper Samples by ICP-MS”. It provides three processed, plot-ready tables used to reproduce the key numerical results and figures in the paper:(1) Sample results: concentrations of ^232Th and ^238U for two copper samples measured under different dilution conditions (reported as mean ± statistical uncertainty, unit: pg·g⁻¹);(2) Blank results: procedural blank results obtained following the same workflow (mean ± statistical uncertainty, unit: pg·g⁻¹);(3) k-coefficient data: correction coefficient k as a function of measurement order under different magnification/dilution settings, enabling correction of systematic bias in repeated measurements and direct re-plotting of the corresponding curve(s) in the paper.The dataset is intended for rapid figure/table reproduction and for facilitating future comparisons or overlaying new data on the same plotting framework.
