Abstract

We have considered the applicability of strontium isotope analysis, using Laser Ablation-assisted Resonance Ionization Mass Spectrometry (LA-RIMS), to the determination of bone origin. We separated the uncertainty into two categories: ion counting statistics, and short-term or uncontrollable shifts of experimental conditions; only the former decreases with increasing signal intensity. Additionally, we confirmed that long-term shifts of isotope ratio in LA-RIMS can be cancelled by an internal correction method. We preliminarily estimated the precision of our technique to be 0.7% (1σ) for 105 laser shots; the accuracy is also confirmed within the present uncertainty through the comparison with a reference value.
