The Specialist Isotopes and Related Services segment focuses on research and development of technologies and methods to separate high-value, low-volume isotopes such as C-14, Mo-100, and Si-28 for target end markets including pharmaceuticals and agrochemicals, nuclear medical imaging, and semiconductors; it also provides related services and operates PET labs. The company offers the Aerodynamic Separation Process (ASP) technology, which separates gas species and isotopes in a volatile state, and the Quantum Enrichment (QE) technology, which separates isotopes. It also produces and commercializes Molybdenum-100, Molybdenum-98, and Ytterbium-176 for the nuclear medical industry. In addition, the company develops Zinc-68, Nickel-64, and Xenon-129/136 for the nuclear medical industry; Lithium-7, Uranium-235, and Chlorine-37 for the energy industry; and Germanium-70/72/74 for semiconductor markets. The company was incorporated in 2021 and is based in Dallas, Texas.
