A gas-free system for separating a solution of substantially impurity-free daughter products from an associated parent load solution includes a pump, a plurality of multi-port valves, separation medium and a processor. An uncoiled conduit extends between a third port of a second multi-port valve and a first multi-port valve. A processor is operably coupled to a pump, and the plurality of multi-port valves. A method for separating a solution of substantially impurity-free daughter product from an associated parent load solution is also disclosed.

Automated radionuclide separation system and method

A method and apparatus are provided for automatically separating radionuclides using a chromatographic separation process. The method includes the steps of displaying a first flow diagram on a display depicting flow of the radionuclides through a first set of separation elements of the plurality of separation processing elements, but only during a first step of the chromatographic separation process and displaying a second flow diagram on the display depicting flow of the radionuclides through a second set of separation elements of the plurality of separation processing elements, but only during a second step of the chromatographic separation process.

Compact automated radionuclide separator

The invention relates to a process for separating and purifying multi-curie quantities,Y of sufficient chemical and radiochemical purity suitable for use in medical applications without a series of,Sr selective extraction chromatographic columns while minimizing loss of radioactive,Sr parent and waste stream. The process includes dissolving a nitrate salt of an original,Sr stock solution in H,O creating a strontium nitrate solution; acidifying the strontium nitrate solution containing,Y with concentrated nitric acid; evaporating the strontium nitrate solution; filtering or centrifuging strontium nitrate solution to separate crystalline,Sr nitrate salt from the solution; evaporating the remaining,Y enriched supernate to dryness; dissolving the remaining,Y enriched supernate in a strong acid; passing the solution through an yttrium selective extraction chromatographic column; rinsing the yttrium selective extraction chromatographic column with strong acid; and eluting yttrium from yttrium selective extraction column with strong acid.

Process and apparatus for the production of BI-212 and a use thereof

A process for producing substantially impurity-free Bi-213 cations is disclosed. An aqueous acid feed solution containing Ac-225 cations is contacted with an ion exchange medium to bind the Ac-225 cations and form an Ac-225-laden ion exchange medium. The bound Ac-225 incubates on the ion exchange medium to form Bi-213 cations by radioactive decay. The Bi-213 cations are then recovered from the Ac-225-laden ion exchange medium to form a substantially impurity-free aqueous Bi-213 cation acid solution. An apparatus for carrying out this process is also disclosed.
