Abstract:
A rapid and sensitive LC-MS approach for the quantification of non-radioactive metal contaminants present in metal radionuclide formulations was developed. Traditional (12)C/(1)H and heavy stable isotope (13)C/(2)H-labeled chelator-amino acid conjugates are used as chelating agents to quantify contaminating transition metals, allowing for determination of effective specific activity of radio-metals.
