A device for on-line electromigration measurements of radioelements in free electrolytes

An electromigration device has been developed for the on-line measurement of absolute individual ion mobilities of radioactive species in free electrolytes. The device is composed of a migration cell, a γ-radiation scanning unit and a data processing system. The performance of two BGO-scintillators as scanning unit and the reliability of an on-line data processing system were studied with calibrated radioactive sources of given velocities. The system was found to work with a high reproducibility rate. The migration velocities were determined with an accuracy better than 1%.
