A fast double-stack chromatographic separation of germanium from silicate material for isotope analysis with MC-ICP-MS

Year: 2026

Type: article

Abstract: Double-stack chromatographic separation combines anion + cation exchange resins to purify germanium from silicate material, delivering quantitative yield, low blanks, and ≤0.10‰ reproducibility on δ 74/70 Ge with MC-ICP-MS and standard-sample bracketing.
