An efficient method for high-precision potassium isotope analysis in carbonate materials
Xi-Kai Wang, Xiaoming Liu, Heng Chen
Abstract
The developed dual-column chromatographic method can purify K in 100–150 mg carbonate materials with satisfactory recovery (∼100%) and negligible blank (∼30 ng) for high-precision K isotope analysis using MC-ICP-MS.
