- Abstract
- <jats:title>Abstract</jats:title> <jats:p>The development of a setup for a fast online characterization of radionuclide generators is reported. A generator utilizing the mother nuclide <jats:sup>227</jats:sup>Ac sorbed on a cation exchange resin is continuously eluted by using a peristaltic pump. To allow continuous and pulse-free elution of a large volume over extended time periods a 3D-printed interface designed to remove pressure-oscillations induced by the pump was placed between pump and generator column to ensure undisturbed generator elution. The eluate of the generator is passed through a 3D printed flow cell placed inside a borehole Na(Tl)-scintillation detector for high counting efficiency. Alternatively, a HPGe detector suitable for nuclide identification was used to demonstrate the validity of the online method. The detection system combines conventional gamma-ray spectrometry with fast list mode data acquisition in the Matlab software package. Elution experiments were performed at different flow rates of hydrochloric acid, separating <jats:sup>211</jats:sup>Bi (<jats:italic>t</jats:italic> <jats:sub>1/2</jats:sub> = 2.14 min) free from its parent nuclides. In addition, to prove the versatility of the setup, experiments at different hydrochloric acid concentrations were performed resulting in the elution of pure <jats:sup>211</jats:sup>Pb (<jats:italic>t</jats:italic> <jats:sub>1/2</jats:sub> = 36.1 min) and <jats:sup>223</jats:sup>Ra (<jats:italic>t</jats:italic> <jats:sub>1/2</jats:sub> = 11.43 d), respectively.</jats:p>
