Copper isotope ratios allowed for quantifying the contribution of coal mining and combustion to total soil copper concentrations in China

Determination of the isotopic composition of copper in a certified reference material HICU-1 by MC-ICP-MS using gravimetric isotope mixture calibration

“…High-precision isotopic analysis of copper plays an important role in the study of various geological, biological and chemical processes [1][2][3][4][5] with applications to geoscience, 6,7 environmental 3,8 and medical 9,10 sciences. Copper isotope ratio measurements are typically performed using either thermal ionization mass spectrometry (TIMS) or multiple collectorinductively coupled plasma mass spectrometer (MC-ICP-MS).…”
