Sr同位素比值(87Sr/86Sr)测试技术作为一项成熟方法和常规示踪技术手段被广泛应用于地球科学、环境科学、考古学等研究中,但该测试技术至今并未开展相应的计量比对工作.为评价各实验室Sr同位素比值检测水平和能力,本文组织开展了地质样品Sr同位素比值测定专项计量比对活动.通过对参加实验室检测结果进行统计分析,评价各实验室的检测能力.结果表明:参比实验室检测结果的满意率为85.7%,仅一个实验室的检测结果为不满意,参比实验室整体检测能力和技术水平良好,但仍然需要重视高Rb/Sr比值样品分离有效性的问题.
Evaluation of the In-ter-laboratory Comparison Results for Sr Isotope Ratio Determination of Geological Sam-ples
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.
