Abstract

Boron is a lithophilic and biophilic element. Boron isotopes in sediments provide insight in the Earth's history. Boron is purified by a combination of cationic and boron-specific resins, and the isotopic composition of boron in sediments can be determined with high accuracy by MC-ICP-MS.
