	abstract = {Increasing interest in 67Cu for targeted radionuclide therapy necessitates development of robust and validated analytical methods to ensure compliance with regulatory standards for clinical translation. We validated methods based on inductively coupled plasma optical emission spectroscopy ({ICP}-{OES}) and high-purity germanium ({HPGe}) γ-spectrometry. For {ICP}-{OES}, criteria were met for most elements, with Al and Ca, suffering matrix effects. Apparent molar activity calculated by {ICP}-{OES} was congruent with {DOTA}-titration-based effective molar activity when Al and Ca were excluded. {HPGe} γ-spectrometry was shown to enable accurate discrimination and quantification of co-produced radionuclides (67Ga, 66Ga, 69mZn) from 67Cu at 99.5\% radionuclidic purity.},
