Abstract
A new separation scheme is presented for the isolation of Nd fractions highly purified from adjacent lanthanides, especially Ce and Pr, in preparation to demanding isotope ratios applications, e.g. determination of 142Nd/144Nd, or measurement of 143Nd/144Nd on very small samples by using NdO+ ion beams.
