They claim they can do <br>gallium purification to extremely high levels in one run, with <br>productivity of 1 kg of pure metal per day. That would mean few hours <br>for our 100-200 g targets. I guess it can be accelerated if needed, <br>either by design, or by parallel runs. The idea would be to run the <br>electrolyzer before the chemical separation, return, say, 99% of pure <br>gallium ready for the next irradiation right away, and then chemically <br>separate Cu-67 from the residuals. That would help increase Cu-67 <br>concentration and make the amount of material for chemical separation <br>small, to avoid known difficulties of working with large volumes.<br>Best regards,<br>Pavel<br><br>_______________________________________________<br>Isotope-prod mailing list<br>Isotope-prod@jlab.org<br>https://mailman.jlab.org/mailman/listinfo/isotope-prod<br></div></div></body></html>
