Abstract

Isotopic analysis by Thermal Ionization Mass Spectrometry (TIMS) requires efficient chemical separation of the element of interest. This statement is particularly true for NdO⁺ measurements during which isobaric interferences must be minimized. Here, we present a new chromatographic procedure that efficiently separates Nd from other Light Rare-Earth Elements (LREE) and is ideal for NdO⁺ measurements. After separation of the LREE fraction from the bulk matrix, Nd is chemically separated using a High Pressure Liquid Chromatographic (HPLC) technique, with Aminex resin (Bio-Rad
