内容記述 Double spike thermal ionization mass spectrometry is a technique that can measure precisely the variation in stable isotopic composition of large atomic number elements. Precision of the double spike technique depends on the isotopic composition of the combined-spikes and also on analytical parameters such as sample-spike mixing factor and combination of the three isotope ratios used in the double spike analysis. Prior to preperation of the double spike, error propagation simulation through the double spike data analyses of Sr, Ba, Nd and Sm is carried out in order to estimate both optimal isotopic composition of the combined-spikes and optimal analytical conditions for these elements. The best isotopic compositions of combined spikes are 84Sr/86Sr double-spike ~2.5, 2.5, 134Ba/136Ba double-spike ~ 2.5, 150Nd/145Nd double-spike ~ 1.0 and 150Sm/154Sm double-spike ~0.47 for Sr, Ba, Nd and Sm, respectively. Optimal analytical conditions are also determined. Reliability of the simulation is confirmed by comparing the Sr error magnification factor of an actual double-spike analysis with the simulation results.
