title: Novel ion exchange chromatography method for nca arsenic separation.
abstract: A high-performance liquid chromatography (HPLC) device equipped with an anion exchange column was used to isolate nca77As from reactor irradiatednatGeO2targets. The oxidation states of the isotope77As 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 isotope74As from cyclotron irradiatednatGeO2targets too.
