一种基于使用uteva规范的方法。介绍了彩色树脂作为固定色谱相的方法。色谱柱与ICP-MS检测器在线耦合，用于测定锕系元素。将该方法与基于使用市售阳离子交换固定相的方法进行了比较。分析方法通过使用认证的标准物质以及其他独立的分析技术进行验证。结果表明，UTEVA-Spec。该柱可同时作为预浓缩柱和色谱柱使用，将分析的检出限降低到几pg g−1。
A method based on the use of the UTEVA-Spec. Eichrom resin as the stationary chromatographic phase is described. The column was coupled on-line to an ICP-MS detector for the determination of actinides. The method is compared with one based on the use of commercially available cation-exchange stationary phases. The analytical procedure was validated by the use of certified reference materials as well as by other independent analytical techniques. It was demonstrated that the UTEVA-Spec. column can be used at the same time as a pre-concentration column, as well as a chromatographic column, lowering the detection limit of analysis down to a few pg g−1.
