A high-performance liquid chromatography (HPLC) device equipped with an anion exchange column was used to isolate nca As from reactor irradiated GeO targets. The oxidation states of the isotope As during the process was verified by thin layer chromatography. The radionuclidic purity of the separated fractions was checked by gamma measurements and it was found to be 99.91% for the As fraction. The elaborated method was applied to separate the isotope As from cyclotron irradiated GeO targets too.
使用配备阴离子交换柱的高效液相色谱（HPLC）装置从反应堆辐照的GeO靶中分离无载体砷（nca As）。该过程中砷同位素的氧化态通过薄层色谱法进行验证。通过伽马测量检查分离馏分的放射性核素纯度，发现砷馏分的纯度为99.91%。所阐述的方法也应用于从回旋加速器辐照的GeO靶中分离砷同位素。
