A fully automated method for the separation of low-concentration uranium from plutonium in environmental swipe samples has been developed. The offline chromatography system features renewable 1 mL Eichrom TEVA and UTEVA column generation from bulk resin slurry. Discrete fractions of the separated actinides are delivered into user defined vials for future analysis. Clean room background levels were achieved outside of a cleanroom environment with this method. Purification of uranium and plutonium from various sample matrixes and at various concentrations was successful. Major and minor isotope ratios for both elements were measured via multiple collector inductively coupled plasma mass spectrometry and were in good agreement with certified reference values. Validation of the separation method was conducted on archived environmental samples and agreed with values previously reported using standard column chemistry.

从环境抽提样品中自动分离铀和P，用于多收集器电感耦合等离子体质谱法

已开发出一种用于在环境擦拭样品中从p中分离低浓度铀的全自动方法。离线色谱系统具有从本体树脂浆料中生成可再生的1 mL Eichrom TEVA和UTEVA柱的功能。分离出的act系元素的分离部分被输送到用户定义的样品瓶中，以备将来分析。使用此方法可以在洁净室环境之外达到洁净室背景水平。从各种样品基质和各种浓度中纯化铀和p是成功的。两种元素的主要和次要同位素比是通过多收集器电感耦合等离子体质谱法测量的，与认证参考值高度吻合。
