摘要：
We have investigated the precision of strontium isotope analysis by Laser Ablation-assisted Resonance Ionization Mass Spectrometry(LA-RIMS). We have confirmed that the mass discrimination effect on the Sr-87/Sr-86 measurement was reduced by the internal correction method.. For the present system, the precision of the isotope ratio of Sr-87/Sr-86 has been estimated to be 0.6% (1 sigma). The precision has been limited by the fluctuations with a time scale of less than 10 s.
