  • Multivalent metal ion extraction using diglycolamide-coated particles
    Patent number: 7553461
    Abstract: A separation medium, a method for using that separation medium and an apparatus for selectively extracting multivalent cations such as pseudo-lanthanide, prelanthanide, lanthanide, preactinide or actinide cations from an aqueous acidic sample solution is described. The separation medium is preferably free-flowing and comprises particles having a diglycolamide (DGA) extractant dispersed onto an inert, porous support.

  • Compact automated radionuclide separator
    Patent number: 6770195
    Abstract: 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.
