Figure 2. Separation of nuclear isomers ¹⁷⁷Lu and ^177mLu.

(a) Schematic representation of the experimental setup (b) ^177mLu/¹⁷⁷Lu activity ratio at continuous elution with a flux of 13.42 mm/min and a temperature of 20 °C. (c) γ ray spectra of the mixture injected in the column with photo-peaks having contribution from both ¹⁷⁷Lu(*) and ^177mLu(#). (d) γ ray spectra of eluted fraction after separation with major photo-peaks from ¹⁷⁷Lu(*), less than 0.5% contribution from ^177mLu.
