Abstract
A generator system for providing a carrier-free radioisotope in the form of an acid comprises a chromatography column in tandem fluid connection with an ion exchange column, the chromatography column containing a charge of a radioactive parent isotope. The chromatography column, charged with a parent isotope, is eluted with an alkali metal salt solution to generate the radioisotope in the form of an intermediate solution, which is passed through the ion-exchange column to convert the radioisotope to a carrier-free acid form.
Claims2
A radioisotopic composition comprising carrier-free Re-188 in the form of perrhenic acid, said perrhenic acid being free of perchloric acid.
A method for carrying out a medical procedure comprising the steps of:
- providing carrier-free Re-188 in the form of perrhenic acid, said perrhenic acid being free of perchloric acid;
- reacting said perrhenic acid with a substance to form a medically useful product;
- and,
- carrying out said medical procedure using said product.
