Evaluation of the In-ter-laboratory Comparison Results for Sr Isotope Ratio Determination of Geological Sam-ples
摘要
Abstract
As a mature method and conventional tracer technology,strontium isotope ratio(87Sr/86Sr)testing technology is widely used in geology,environment,archaeology and other research,but there has not been a countrywide intra-lab comparison work for this analysis method for a rather long time.To evaluate the stron-tium isotope ratio testing ability of laboratories in various laboratory,a comparison activity for geological samples has been organized aiming for the strontium isotope ratio determination by statistically analyzing the test results of the participating laboratories.The results show that,among all the data of the yielded Sr iso-topes value given from 7 laboratories,85.7%of them have met the requirement except only one laboratory with unsatisfactory results,indicating that the overall testing capacity and technical level of the participating laboratories are good,but more attention should be paid to the issue of the validity of the separation of sam-ples with high Rb/Sr ratio.关键词
