Measurement of Zr isotopic composition in geological samples by MC-ICP-MS using a TOPO-based single-column protocol
Yu-chen Xiao, Qiao-hui Zhong, Jia-kai Guo, Gao-bin Chu, Jie LiSingle-column Zr separation with TOPO resin (rinsed/eluted with 3 M HNO 3 /1 M HCl and 3 M HNO 3 + 0.1 M HF) and MC-ICP-MS with Sr normalization (C-SSBIN) yields ±0.061‰ (2SD) for geological reference.
