| Abstract | We present a precise and accurate method for the determination of 143Nd/144Nd isotope ratio without Nd and Sm separation by multiple collector inductively coupled plasma mass spectrometry. We corrected instrumental mass discrimination by applying the natural constant 146Nd/144Nd ratio as an internal standard after isobaric interference correction of 144Sm on 144Nd using interference-free 147Sm/149Sm ratio for Sm mass fractionation. The present method was validated by duplicate analyses of several certified reference materials after dissolution and cation-exchange resin purification. The precision (2σ) of the 143Nd/144Nd ratio is less than 10 ppm (internal) and 20 ppm (external), respectively. |
