An automated procedure for the determination of (90)Sr was adapted from existing methods of flow scintillation analysis (FSA) for use on aqueous samples with low levels of activity (<1000 dpm per sample). This technique employs high-performance extraction chromatography (HPEC) and an on-line liquid scintillation counter to provide automated separation and subsequent detection of (90)Sr. The total analysis time is 30 min per sample. Dilute urine samples, spiked with (90)Sr, were also processed by this method to test the application of this technique for bioassay monitoring.
一种用于测定（90）锶的自动化程序是从现有的流动闪烁分析（FSA）方法改编而来，用于分析低活度（每个样品<1000 dpm）的水性样品。该技术采用高效萃取色谱法（HPEC）和在线液体闪烁计数器，以实现（90）锶的自动分离和后续检测。每个样品的总分析时间为30分钟。还通过该方法处理了添加了（90）锶的稀释尿液样品，以测试该技术在生物测定监测中的应用。
