  • High specific activity platinum-195m
    Patent number: 6804319
    Abstract: A new composition of matter includes 195mPt characterized by a specific activity of at least 30 mCi/mg Pt, generally made by method that includes the steps of: exposing 193Ir to a flux of neutrons sufficient to convert a portion of the 193Ir to 195mPt to form an irradiated material; dissolving the irradiated material to form an intermediate solution comprising Ir and Pt; and separating the Pt from the Ir by cation exchange chromatography to produce 195mPt.
    Type: Grant
    Filed: November 20, 2003
    Date of Patent: October 12, 2004
    Assignee: UT-Battelle, LLC
    Inventors: Saed Mirzadeh, Miting Du, Arnold L. Beets, Furn F. Knapp, Jr.

  • Method for preparing high specific activity 177Lu
    Patent number: 6716353
    Abstract: A method of separating lutetium from a solution containing Lu and Yb, particularly reactor-produced 177Lu and 177Yb, includes the steps of: providing a chromatographic separation apparatus containing LN resin; loading the apparatus with a solution containing Lu and Yb; and eluting the apparatus to chromatographically separate the Lu and the Yb in order to produce high-specific-activity 177Yb.

  • Concentration of perrhenate and pertechnetate solutions
    Patent number: 5729821
    Abstract: A method of preparing a concentrated solution of a carrier-free radioisotope which includes the steps of:a. providing a generator column loaded with a composition containing a parent radioisotope;b. eluting the generator column with an eluent solution which includes a salt of a weak acid to elute a target daughter radioisotope from the generator column in a first eluate.c. eluting a cation-exchange column with the first eluate to exchange cations of the salt for hydrogen ions and to elute the target daughter radioisotope and a weak acid in a second eluate;d. eluting an anion-exchange column with the second eluate to trap and concentrate the target daughter radioisotope and to elute the weak acid solution therefrom; ande. eluting the concentrated target daughter radioisotope from the anion-exchange column with a saline solution.
