Abstract
The experimental conditions for minimizing errors in the laser mass spectrometric (LMS) analysis of isotopic ratios for Nd and Yb were found, and the optimum isotope pairs for determining these elements with the use of isotope dilution (ID) were chosen. The precision and accuracy of LMS data, which are characterized by relative random errors (RSD) and relative systematic errors (δ), can be improved using ID. The values for Nd or Yb were no higher than RSD = 2.9% and δ = 0.024 or RSD = 5% and δ = 0.097, respectively.
